sierra248 Posted August 14, 2004 Posted August 14, 2004 (edited) Well the highest Stable I can run is 2.8c @ 3.221 DDR460 @ 1:1 with all the performance stuff turnerd all on in bios and it runs dual prime 95 for 48 hours with no errors and passes all memtest test. Memory is at OCZ PC3700EB 3-3-2-4-4 @2.65volts. The reason I cannot run over 230FSB is because it takes to many volts to get there, though it will boot at 1.80volts, I was afraid to Bench it for more then a minute or 2. Anything less and i get the all to familiar Blue screen or hard drive not found boot errors. When I run Prime-95 and CPU Burn -in it runs at 100% stable at 230 and 1.60volts but MotherBoard Mon. Shows it go as low as 1.50volts. When I booted at 250 I slowed the memory speeds to slowest and even tried different ratios and i cannot run at 250 without at least 1.80volts, but the CPU Temp never got above 114(45.5 Celcius) and that was the highest, it averages at 100% CPU around 110(43.33 Cecius). IS there a chance I just got a chip that needs extra volts. I special ordered this (2.8c SLZ65 as I was told it would almost be guarenteed to OC to 250. This is the thing Ive tried evgeryons suggestions about disable spread spectrum and run higher latencies to get ther but I really wanted 250MZ DDR500 to take advantage of the high CPU speed but also the increased Memory Bandwisth, so i am a little disapointed. I think I have tried every combo in the bios but the only one that works is more VOLTS. I'd like the chip to last for at least a year or so but am willing to sacrifice a little length of life for performance now. My questions is to all you P4c800-e guys is, Would the Volt Mod help me in my quest for 250mhz? I know it just helts to stop the dropping of the voltage during use on the CPU, but would it help someone in my situation? And While I am at it I think Ill do the Memory Volt mod while I'm at it (Or whoever I have do it, I shake to much to try that) so I can run my memory at 2.5-2-2 which with 3.1 or 3.2 volts is supposedly easily achieved. This is where I am at now and its 100% stable on All Memtest and Prime95 with CPU Burn-in running also. Let me know what u all think, I love new suggestions. Sry this is so long but i really like your opinions and want to not leave anything u need to correctly answer my questions. Plus probably allot of p4c-800-e guys that would like to know some of this stuff.
