  1. Enter the BIOS. Go to Advanced Chipset Features and set Memory Hole for PCI MMIO to Enabled. Save Changes and Exit.
  2. Posted at http://www.dfi-street.com/forum/showpost.p...0&postcount=485 if it is of any help to other Opty 165 users.
  3. As the title says, I'm happy with the performance of this Opty 165 received over a month ago. It's gone as far as 3006Mhz (9x334/273) on as low as 1.475Vcore (Windows), but it is NOT Prime95 stable, which is my goal so I can finally OCDB this setup. Increasing the Vcore to 1.525V in the BIOS results in a "rounding error" only moments (3secs-5mins) in P95 on Core 0 (the hotter of the 2 cores). It will run BF2 for hours on end, without complaint @ only 1.525Vcore. Weird.... Upgraded from a single core Opty 148 to a dual core Opty 165, so if the reader is doing the same, maybe these specs will help them with their overclock. Let me point out that switching from the Opty 148 to Opty 165 with the G.Skill 2GB HZ RAM, I found that DDS, MAL and the Read Preamble settings to be CRITICAL. Increased DDS from 3 (Opty 148) to 7 (Opty 165). Setting DDS to any other setting than 7 results in major errors in M86 and hard lockups in Windows....even at stock speeds. Also had to relax both MAL and RP considerably or it would error out in M86 and hard lock Windows. Also found DRAM Response Time set to Normal NEVER booted when I used the Opty 148; only Fastest and Fast worked. Moving to the Opty 165 Normal, Fast and Fastest work with no problems. Practically every other RAM setting is identical to what I used for the Opty 148. See my 2 other posts in this Thread for more info on the Opty148/HZ setup. Here are my current stable specs and if there is something I may have overlooked, I'd appreciate the advice. ***Wherever you see a "<" at the end of a setting; this was my attempt to 3Ghz.*** Motherboard: DFI LanParty UT SLI-DR Expert CPU: AMD Opteron 165 (CCBBE 0615DPMW) RAM: 2x1GB G.Skill HZ PC4000 (Build 0604) SPD: 250Mhz @ 3-5-5-10 Real Ram Mhz: 266 BIOS Version: 12/07/05 FSB Bus Freq: 325 LDT/FSB Freq: 2.5 CPU/FSB Freq Ratio: 9 PCI-Express Freq: 101 CPU Mhz: 2925 Mhz (Stable in everything) Cooled by: See sig; Remains unchanged.

(/usepmtimer also manually added to Boot.ini file just to make sure.) M$ Hotfix: Haven't tried, but not having any problems. AMD Dual Core Optimizer: No, causes hard lock in Windows. Haven't seen any performance drop from not using the drivers or hotfixes, but the exact opposite. Maybe I'm lucky? Followed the proper method of installing the "fixes" in both here and XtremeSystems. ...or should I just give up and be happy with what I got? Watercooling or popping off the IHS is not an option I'd be willing to explore at this time. ***Edit - Forgot to add that the temps I posted above are @ 2.925Ghz. @ 3Ghz, Core temp v.93 shows 50C for Core 0 and 47C-49C in Core 1. MBM5 never exceeds 47C in Settings High/Low. Core 0 is the one that fails in P95 Blended. I've reseated the HSF a couple times (cleaned and prepped with fresh AS5 each time) without any changes in temps.

  5. As I had promised in an earlier post, here are my settings for running at lower RAM mhz with tighter timings. Increased both LDT and Chipset V from my previous post to complete 3DM '01. It passes the other BM's with the LDT @ 1.2V and Chipset @ 1.59V set in the BIOS.

  6. Go here: http://www.dfi-street.com/forum/showthread.php?t=41953 At the bottom of the 1st post there is the GSkill 2x1024 HZ cheat sheet v1.04 03-27-2006.zip which can be opened in either Excel or OpenOffice. I'd suggest printing it out so it's handy when you're in the BIOS. There are many threads similar to the above at other overclocking forums. G.Skill HZ is very popular so Google is your friend. I've collected 40+ screenshots and this was back in January, so you should have no problems with ideas to start from. Start at the lower mhz for RAM and work your way up. It usually takes me about a month or so before I can find my maximums, so have patience. Set your expectations low and your hopes high. This RAM is guaranteed to hit 250mhz @ 3-4-4-8 so anything better than that is a bonus, but not guaranteed. If it always performed better, they would bin the RAM as such and charge a higher price. The same holds true for any PC component. Overclocking is a game. I've been in the game since "gold fingers" came out. Sometimes you win, sometimes you lose, but you always learn something new so just have fun with it.
  7. When running Super Pi is the CPU at full load (%100)? RAM just feeds data to the CPU to process. If it only takes 8388648 bytes of RAM to keep the CPU full of data to crunch on, then allocating more RAM isn't going to improve performance. Think of a steam engine. The engine is the CPU and the RAM is the coal. Once the engine is outputting at maximum pressure, adding more coal to it doesn't make the train go faster. If you're looking to improve performance, then increase the CPU mhz so it can crunch faster.
  8. http://www.techpowerup.com/reviews/GSkill/4000-2GBHZ/ is the review on G.Skill HZ ram at Techpowerup, not the one posted above.
  9. I'm on my 2nd set of G.Skill HZ. The 1st set was purchased right around Christmas (~$190) and ran 263/263 in dual channel and had the original SPD of 250Mhz @ 3-4-4-8. When testing as single sticks, one topped out at 277mhz (Build 0509) and the other at 260mhz (Build 0510). Yes, these were purchased as single packs and not in the dual pack configuration, because at that time, Newegg was sold out. Ran into no issues with this G.Skill HZ so long as I didn't go beyond the above limits. Since I needed another 2Gigs of RAM, I had no problem pulling the trigger again on HZ, but this time I went for the dual pack configuration. My second shot scored higher on the target. This dual pack was received during the 1st week of May and are Build 0604.

Still fiddling with finding Max Mem Mhz and tighter timings at a lower frequency. With these summer temps approaching, I fear I may have already run out of time for finding Max OC on air. I suicided at 3050mhz and could even run stable at 3014mhz with the old set of HZ....and room temps of 13-15C (55-59F). With a few quick attempts made last week, it was having trouble posting beyond 2970Mhz, but I'd only dedicated about 30mins to it.
