dæmon Posted April 26, 2005 Posted April 26, 2005 Hello, my first time posting here...I am running an a64 3000+ on an ultra-d with some OCZ pc4000 gold vx...here's the thing though: the ram sticker says PC4000 GoldVX but with timings of 2-3-3-8...I know the ram is rated at these timings at default voltage (2.6), so is this why the sticker says this? or did i just get duped out of the ram i payed for (the 2-2-2-8)? Anyway, I have been able to push it up to 250x9 = 2250MHz at 2-2-2-8, with the voltage at 3.3V for the memory and 1.4V + 110% for the CPU...Ran Counterstrike source for about 2 hours then emule and prime95 all night stable, but firefox did crash once earlier in the night...using a thermaltake venus 8+ with the stock paste but CPU didn't go above 45C...I cannot use memtest or update the BIOS as I do not have a floppy drive right now 260x9 booted but doom3 froze and i just put it back to where it was at 250...it seems I am limited by the low 9x multiplier...I tried lowering the DRAM/FSB ratio from 1:1 to 9/10 and then 5/6 but the system didn't like this and wouldn't boot...any ideas how i can push the cpu without increasing the FSB frequency? any help or suggestions would be appreciated. Thanks in advance.

solsource Posted April 27, 2005 Posted April 27, 2005 Memtest also comes in a bootable cd version. Just go to their website. That was the one I used to use. If you have Nero or other cd burning program (if you have emule im sure u know where to find one :cool: ) just burn the iso as a bootable cd. Then change your settings in bios so that your comp will boot from cd BEFORE booting from Hard Drive. I am not a very experienced overclocker but I have corrupted a few windows installations by booting into windows without testing my overclock stability. I just do about 2 passes in memtest (takes about half an hour) then i go onto the windows stability tests and benchmarks (prime95, SuperPi, 3dmark, sisoftsandra- all free). Sorry I can't help you with your overclocking problem just thought this would help. Quote Share this post Link to post Share on other sites More sharing options...
Vista Posted April 27, 2005 Posted April 27, 2005 http://www.memtest.org/download/1.55.1/mem...-1.55.1.iso.zip This is the ISO you need to burn a bootable CD-ROM or DVD image using Nero, etc. It is the preferred Memtest 1.55.1 that is on the 331 and 414 BIOS, versus the 1.51 version that is on the 310 BIOS. If you try MemTest86 3.2 from memtest86.com, be aware it doesn't detect RAM speed and timings, though otherwise seems identical to 1.55 in stability. All that being said, Memtest 1.55.1 is very stable, and a good tool for preflighting your RAM/CPU/PSU before attempting Windows takeoff. Test #8 seems to be the most intense, so I just loop it. There are weird graph bar text overwrite problems on Test #8 using the built-in Memtest 1.51 on BIOS 310, while booting off a CD with Memtest 1.55.1 and BIOS 310 has no graph bar update anomalies. I haven't tried it using 1.51 booting off a CD, the text bar graphic glitches didn't affect the error-detection abilities of Memtest 1.51 on the 310 BIOS, just visual annoyances.

chennhui Posted April 27, 2005 Posted April 27, 2005 dæmon, Athlon 64's multipler is downward unlock, as a results, you can't increase CPU speed without increasing the HTT. Newer winchester required higher cpu voltage to reach higher clock. In my case, my CPU voltage is around 1.64v (as reported by ITE). Your RAM PC4000 should not has problem reaching 280 ranger. Which slot are you using for the LSI Logic U160 SCSI Adapter? I am interest to purchase a scsi adapter.. Quote Share this post Link to post Share on other sites More sharing options...
dæmon Posted April 27, 2005 Posted April 27, 2005 I am using the lowest PCI slot for the LSI...I got a great deal on all my SCSI stuff, check it out: LSI Logic U160: $50 @hypermicro Refurbished 15k.3: $130 @hypermicro (sold out last time i checked) 10K 74GB: $70 from pricewatch Quote Share this post Link to post Share on other sites More sharing options...
chennhui Posted April 29, 2005 Posted April 29, 2005 But the maximum bandwidth for PCI is 133MB/s. You U160 has exceeded the maximum bandwidth... and I believe PCI 133Mb/s is not a sustainable bandwidth. I am using the lowest PCI slot for the LSI...I got a great deal on all my SCSI stuff, check it out: LSI Logic U160: $50 @hypermicro Refurbished 15k.3: $130 @hypermicro (sold out last time i checked) 10K 74GB: $70 from pricewatch Quote Share this post Link to post Share on other sites More sharing options...
