SilverSliver Posted February 24, 2004 Share Posted February 24, 2004 Well, here's my setup Abit IC7-G -- new bios, rev 1.1 board P4 2.4C Corsair TwinX Platinum PC3200 C2PT 2:3:2:6 @ 2.8v ( 1 gig dual channel ) Hercules 9800 Pro Augidy 2 -- Now heres my issue -- Set 2.4C at 250 FSB. 5:4 divider will NOT work. 3:2 divider will work. 250/167 respectively. Under no circumstance have I been able to stabalize the 5:4 divider. Well...If I run the FSB at 230, and the ram at 180, it is stable but not as fast as the 3/2. I've also tried the 5:4 divider, 250/200 with ram timings of 3/4/4/8 with no luck. What is my issue here? Why can I not get this ram to reach its STOCK speed rating when I OC the FSB. It seems like the cut off point is around 182 or so for the ram. And, I have the following in my BIOS tweaked.. PSB800 AGP/PCI fixed ram bios caches disabled, read and clock disabled under gaming. -- What else can I do? Im not upping my FSB anymore until I get my Spark 7 HSF in the mail, as I think I could run 280 or so FSB with ram approaching 180, but I'd prefer really a lower FSB with decent ram speed. What can I do? What am I doing wrong? Link to comment Share on other sites More sharing options...
Lucifer_v1 Posted February 24, 2004 Share Posted February 24, 2004 Reset Bios Lock the AGP/PCI, VDIMM at 2.8 Set GAT to A-A-A-D-D Default GAT setting (ie. dont use F1 or Turbo) AGP Volts need to be 1.65 Use default RAM timings to start off. AGP/PCI should be fixed at 66/33 Disable Fast-Writes All I can think of right now, let me know how it goes. Link to comment Share on other sites More sharing options...

It won't even work with VERY relaxed timings at 250/200. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 24, 2004 Corsair Employees Share Posted February 24, 2004 Please try testing the modules one at a time at default settings on the CPU and the memory Freq set to 1-1- or at DDR400 and set the timings manually to Cass 2-3-3-6 and test with [url]www.memtest.org[/url] and lets make sure it's not a bad module. If they both pass that would suggest that the MB may not be able to run at those settings. Link to comment Share on other sites More sharing options...

Yet the ram is being unstable when running 3dmark03. Im not understanding the problem... =/ Link to comment Share on other sites More sharing options...
Lucifer_v1 Posted February 25, 2004 Share Posted February 25, 2004 You may just need more volts mate. What is your VCore at? Stock? May want to give the VCore a tiny bit more juice if that's the case. The RAM doesn't sound like it's the issue since you stated it is running at rated speed with no errors.

Abit's undervolt, so, I might throw some more juice at the thing and bump it 1.6v on the core. 1.55 wasnt enough. I'll wait til my new Spark 7 comes in though.

Lucifer_v1 Posted February 25, 2004 Share Posted February 25, 2004 Yeah, 1.6 is what I was going to suggest. I have seen people get 1.65 on stock HSF but it's rare. Try 1.6 and see if that sorts you out. Good Luck! Link to comment Share on other sites More sharing options...
