  1. Its weird, Memtest86+ gives me millions of errors in test 3, and plenty in test 5 & 8, and test 1 & 2 don't throw up any errors (and i don't remember the others). Right now I have the rig OC'd 3.4 (425x8 @ 1.325v Ram: 6/5 @ 510mhz) and its 16 hours prime95 stable, 3 hours dual memtest stable, OCCT stable (1 hour: blend, CPU & RAM) & everest System Stablity test stable. I have also had it 8.5 hours prime stable OC'd to 3.6 (450x8 @ 1.375v Ram: 6/5 @ 540mhz) Now, to me, this says that i have a stable rig no matter what memtest86 says. But it still drives me a bit nuts, knowing that memtest86 is getting errors. I also did another test with Microsoft Windows Memory Diagnostic and it throws up errors similarly to memtest86+. So, i haven't been able to put full trust into all the stability tests - its about 98%. And at the same time i can't deny that i am 16hrs prime & 3 hours dual memtest stable. I just want to know what is causing it. I do have an idea about it, i just haven't confirmed it yet. My suspicion is that the problem is that i am running memtest86 & MWMD from a SATA dvd drive. I don't have a flash drive to run them from (I think this may be the excuse i finally need to get one) and I need to grab the floppy drive out of my wife's puter to test it. Maybe i'll do that tonight instead of tomorrow. But anyhow, I have had an aweful lot of fun clocking this thing, and learning the intel side of things. This is the first intel machine that i have built and had a chance to OC. This thing runs like a champ. I'm dying to get this thing watercooled to see what more i can do with it... I'm sad that i will be turning this over to my buddy on Friday....
  2. So i have now discovered that the real problem I have is with memtest86+. I finally gave up and installed windows, installed the mobo drivers and checked all the RAM timings with memset & cpuz & everything looked good so i fired up prime95 and it ran for 6 hours (at 1066 default timings) before i stopped it . I also tested the ram at 700, 800, 850 900mhz and no errors with prime95. Obviously i can't trust memtest86. So, yesterday i got everything up and running and have been tweaking, got her up to 3.4 pretty stable (3 hours prime95) with barely a bump in voltage and now am working on 3.6. Thanks for the help!
  3. I downloaded the latest bios a little bit ago and i'm going to try that next...
  4. I will try increasing the voltage a little bit, but truthfully, if the sticks won't run at the rated voltage but will with a boost, i don't trust that they will last, thanks for the suggestion. So i have done a bit more testing and i'm not sure that the ram is the issue, when i run memtest on each stick individually, i consistantly get the same errors during the same part of the test. For instance no errors at all until test #3 @ 55%, then a bazillion errors, same thing with test 8, get the same errors for both separate sticks. Now i am suspecting that the problem doesn't lie with the RAM, but maybe with the motherboard. Any one else have an opinion on this?
  5. Nice tutorial, I'm going to have to give this a try with my hellgate disc and see if it works. Thanks for the effort.
  6. Well its been a long while since i have been around, and I am sure hoping you all can help me with a problem i am having... So here is the situation: I have just built myself (actually for a friend) a new system and am using the Gigabyte P35 DS3P motherboard with the Dominator TWIN2X2048-8500C5D & a C2D E6750. No matter what i seem to do i get lots of errors in memtest86+ (v2.00). I have tried loading optimized defaults, failsafe defaults and manually setting the timings 5-5-5-15 (at least the primary 4, haven't messed with the others yet). I have tried running the RAM at 667mHz, 800mHz & 1066mHz. I have also tried testing each stick individually and manually setting the voltage. All this and i still get memtest86+ errors. A couple of things to consider: This is the first C2D Intel machine i have assembled and tweaked, though I can barely claim to have tweaked this. This is my first Gigabyte board (I am used to the Asus & DFI BIOS). This is my first real experience playing with and tweaking DDR2 Ram - (I am used to DDR1 so the timings seem huge, i understand why, but my perspective is still adjusting). So keeping all those things in mind, i may just be making some really newb mistake, but i can't see it. What is the likelyhood of both modules being faulty? (Seems fairly low to me, but it looks like alot of these dominators have a higher then usual failure rate) What timings i should enter in BIOS? (or should optimized defaults be good enough?) Is this a Mobo issue? I am not necessarily convinced that it is the RAM, but... I would like to try to narrow down the issue to prevent lots of RMAs (and extending the weeks to get this thing finished), the trouble is, i don't have any DDR2 ram laying around or any spare LGA775 mobos since all of my rigs are still AMD using DDR.

  7. Now this is the DISHONESTY that we were talking about earlier. If it doesn't OC the way you want it to, but it does the stock speeds just fine KEEP IT. Sell it on ebay or the FS/FT section, but DO NOT RETURN IT. If you want a guaranteed 2.8, then buy an x2 5600. Buying cpus to OC is a crap shoot. Sometimes you win, sometimes you don't and if you don't, it doesn't give you the right to return the chip because it doesn't OC as well as you want it to. It does the stock speeds right? Then you got what you paid for. RETURNING CPUS THAT DON'T OC AS WELL AS YOU WANT IS DISHONEST AND UNETHICAL
  8. Got the PSU 2 days ago, Thanks David. I haven't installed it yet, but probably will in about a week. oh yeah, Bump
  9. Exchanging or returning that processor because he didn't get the stepping he wanted isn't dishonest. He has every right to return the processor if he wants to, provided that he doesn't open the box or try to install it. NOW, If he installed it & it didn't OC as well as he wanted it to so he returned it - That would be dishonest. If he returns it because he didn't get the stepping he wanted, so be it. It is not dishonest. It is only going to cost him more money - him and nobody else. If he is ok with the additional cost & understands the he may get another stepping that he doesn't like, well that is his choice. Neweggs CPU return policy.
  10. You cannot adjust the memory controller voltage separately, the mem controller is part of the CPU. The Vcore is the only setting that controls the voltage sent to the CPU. The Hyper Transport (HT) is the bus that connects the CPU to the RAM. No, the above explaination also applies here as well. 41c seems way too low for 1.65v. Maybe you have a magically cool chip but... I have a really hard time accepting those temps & wonder if they are inaccurate. Again, what does Coretemp report?
  11. No, not at all. Especially not on air. I think that your problem lies in your memory timings or in the fact that you are using 4 dimms or both. On air I wouldn't run more then 1.5v for daily use & on water I wouldn't run more then 1.6v for daily use. *edit what does coretemp report your temps as? Yes phase is a kind of cooling: Phase change The reason you have to keep bumping the volts is because 4 dimms puts considerable strain on your mem controller, therefore more volts to get it stable.
  12. Great work jubbin Did you also run 3DMark on each divider? I would like to see how it responds to changing the mem bandwith... As for AG's sticky, been a long time since I read it, but I remember one of the points he made was that you will get better performance by OCing your CPU with your RAM on a divider then if you ran your RAM 1:1 with a lower CPU OC. He was also looking at tight vs. loose timings and demonstrated that timings don't have nearly as big of an effect now that the mem controller is on the cpu.
  13. Very short version: http://www.tgdaily.com/2007/02/23/china_el...ternet_addicts/ Long version: http://www.msnbc.msn.com/id/17251571/page/1/ You really should read both articles, not just the short version ------------- WOW. Treating it like it is similar to a heroin addiction... I'm not saying that 'internet addiction' isn't a problem in china, but the treatment seems pretty harsh to me. Makes me happy to not live in china...
  14. http://www.diy-street.com/forum/showpost.p...829&postcount=3 Damn crappy CCBWE 0550 steppings... It took me a almost 2 weeks to figure out how much memory timings actually affect a CPU's overclock...
  15. Yep, it is scaling like you have reached the CPUs limit. A new bios is probably worth a try, but probably won't make a huge difference.
  16. My HZs are the same way, they like less voltage, not more. You & I have very similar rigs except for motherboard & our settings are very similar as well. As for ram timings the only difference is: RP = 5.5 DRAM DDS = 2 DRAM volt = 2.55 Also my LDT volt is 1.2 & Chipset is 1.52. I am wondering if maybe the ram isn't happy... What happens if you bump your ram volts up a touch: 2.55-2.6? I know mine seem to be fine between 2.55 & 2.6, but they don't like lower then 2.55. 280x10 is stable @ 1.475, What kind of volts does it take to get 290x10 stable?
  17. I didn't even notice your PWMIC or chipset temps.... They are out of control too. Well, not so much your chipset temp, that is pretty normal for the stock chipset HSF. But the PWMIC @ 68c :eek2: What happens when you take the door off your case?
  18. lol @ 80 3dmarks in 06 :shake: :shake:
  19. Well, I definitely think it is your temps that prevent you from getting the higher clocks stable. A new HSF will probably let you get a higher OC before a new PSU. I'm not saying you don't NEED a new PSU - you definitely do, but with your temps where they are, you won't get the OC stabilized even with a new PSU. I say get a new PSU (600w+) & HSF - Turniq tower, TT BigTyphoon, etc.) Seeing your Coretemps & SG temps gives you a really good idea of how far off your thermistor is...
  20. I still think it is your PSU holding you back at this point... Especially with the 1950xt sucking down juice. Although, looking at your temps in Coretemp, it is more then the PSU holding you back, it is also your cooling. What are you using to cool that chip anyway? What are you temps as reported by smartgaurdian? I agree with Chump, if you are failing SuperPi, you are nowhere near stable.
  21. Well, the 450w Modstream is definately not enough for your rig... It wouldn't surprise me if it is limited your OC. This is not to say that your chip won't do 2.6, it very well may not, but you still should upgrade your PSU. Then you will know for sure! Grab a high quality 600w or 700w PSU & see if it makes a difference.
  22. I read alot about how the 7/16" tubing is a real classy lady to get on the barbs & even more difficult to get back off. the only problem I have with it is getting it on the plastic barbs like the T line & barbs on my Storm. And even then warming the tube up makes it a lot easier. I recently read a nice tip that I will be trying next time I redo mine or do another - Putting a small amount of KY Jelly on the barb to make tube slip on easier... However.... I have never used 1/2" tubing. I might try it & turn around and say "What the hell was I doing all that time messing with 7/16"!?!?" I am using the 7/16" Masterkleer
  23. Well, not sure about the BIOS not seeing 4 gigs... guess you'll have to do some searching around here to see if anything turns up. If you can't find anything, It will be worth starting a new thread about it - you'll probably get a lot more views then you are in this thread.
