Capt Proton Posted October 1, 2006 Posted October 1, 2006 I have been getting my new rig (in sig) going. Got 300 X 10 Prime Stable, but not 3D stable. Memory running 250MHz. Noticed that 3D Mark 03 "Wings of Fury" looped would give me the problem consistently. The Problem. Stuttering, freezes, where the screen freezes for a while and then starts again further into the test (reminds me of the 6800/NF3 issue), or a BSOD. Vid Card at stock. BSOD screen "The device driver got stuck in an infinite loop", Bunch of numbers, and NV_4disp. Thought maybe a driver issue, reloaded drivers, installed older drivers (removed in control panel and Driver Cleaner in Safe Mode) No help. Maybe CPU. Gave more volts, backed off on the divider. No help. Set HTT to 250MHz, CPU Multi to 8 (stock speed). No help. Lowered HTT to 245MHz, problem gone. So, it must be a Memory timing(s). Timings as follows FSB Bus Frequency............................. 250 MHz LDT/FSB Frequency Ratio....................... Auto CPU/FSB Frequency Ratio....................... 10 PCI eXpress Frequency......................... 100 CPU Voltage .................................. 1.400v LDT Voltage .................................. 1.30v ChipSet (NF4) Voltage ........................ 1.60V DRAM Voltage ................................. 2.80v +0.03 if not 3.2V ............................ enable Memclock (DRAM Frequency) .................... 200 1T/2T Timing (Command Per Clock).............. 1T CAS Latency (Tcl)............................. 3T RAS# to CAS# delay (Trcd)..................... 3T Min RAS# active time (Tras)................... 8T Row precharge time (Trp)...................... 3T Row Cycle time (Trc).......................... 11T Row refresh cyc time (Trfc)................... 16T Row to Row delay (Trrd)....................... 3T Write recovery time (Twr)..................... 2T Write to Read delay (Twtr).................... 2T Read to Write delay (Trwt).................... 3T Refresh Period (Tref)......................... 3120 DRAM Bank Interleave.......................... Enabled DQS Skew Control.............................. Auto DQS Skew Value................................ 0 DRAM Drive Strength........................... Normal 4 (called Level 8 in other bios') DRAM Data Drive Strength...................... Level 2 Max Async Latency............................. 8ns DRAM Response Time............................ Normal Read Preamble Time............................ 6ns IdleCycle Limit............................... 256 Dynamic Counter............................... Disable R/W Queue Bypass.............................. 16x Bypass Max.................................... 4x 32 Byte Granularity........................... Disable (4 Bursts) Any thoughts on whch to start playing with? Share this post Link to post Share on other sites More sharing options...
oc newbie Posted October 1, 2006 Posted October 1, 2006 If your temp's are good you might try nudging your voltage a little, sometimes it need's a little nudge in voltage to get 3d stable. My cab1e does that when I try for anything over 3170 but I think it is the limit on this chip. Still gonna shoot for 3200 in an expert board though. edit-Missed the part about already tryin more volt's sorry about that. Might be hitting the limit of the chip.

Capt Proton Posted October 1, 2006 Posted October 1, 2006 Not when its running at or below 2GHz, as stated. Share this post Link to post Share on other sites More sharing options...
ollietwinam Posted October 1, 2006 Posted October 1, 2006 Have you tried putting the RAM on a divider? Share this post Link to post Share on other sites More sharing options...
Capt Proton Posted October 1, 2006 Posted October 1, 2006 Absolutely. I have not tried to run the memory at over 250MHz since I put the build in the case. I had it running at close to 260MHz when I was testing outside the case for the intial build, but I only ran CPU at stock, as I only had the stock HSF installed. In addition, I did not run any 3D apps until I had it all installed. It was Memtest, OCCT, and Prime stable. Still is. Just not 3D stable unless the memory is runnign around 245MHz. I have been trying looser settings, but, so far, no luck. I had a similar problem in my Newark/Infinity 4X build. I never did get the system above 248MHz, and it slowly started dropping to a MHz or so to maintain stability. I blamed it on the board and the CPU, but, maybe the memory has been the culprit all along. Worth noting here that the timings I was running in my old build, which never did run stable at 250MHz, were a little tighter than what I'm trying to get now, which are the recommended settings from OCZ for the NF4 and this memory. And, before anyone jumps, I know that timings in one rig, or one BIOS, won't neccessarily act the same in another build and/or BIOS. I'm not that much of a noob. I alos tried using the yellow slots, as there was some advice from teh OCZ reps on the Bleedin Edge forums that this BIOS runs better in them, but, if anything, it crashed even quicker.
