XMS 4000 settings


Recommended Posts

it would be good to know which board you have? that being said, here's some timings for you to play with: these were provided from a buddy of mine at amdmb.com: @stock/auto for everything except timings, i've run the 4000pro sticks at 2-3-3-5; 2-3-3-6; 2.5-3-3-6; 2.5-4-3-6; 3-4-4-8; and 3-5-5-6 with no problems at all. running in slots 1 and 3.

I have run PC4000 on my Asus P4C800 Deluxe at DDR534/FSB267. The Vdimm was 2.75v and timings were 2.5,3,4,7 (in the AMI bios, on other boards not using AMI bios it's the same as 2.5,4,3,7). I have actually gotten my best benchmarks at 2.5,3,4,8. Not sure why 8 is better than 7 but it works. What MOBO do you have? Mike.

hi! first thx for your comments! I use a P4C800-e Deluxe Bios rev. 1016, and a P4 2,8 E I tried 250 fsb 2,5/3/3/6 with 2,75v, but the board didn´t post... with 3/4/4/8 it posts and works rock stable up to 270 fsb, so it can´t be the cpu... but I want to use fsb 250 with better latency... eddie

what are your vcore and ram voltages at? you may need to pump them up to do what you want to do..this memory will run at faster timings..but it is programmed at the 3-4-4-8 speeds and nothing else..i say that because if you look at the cpu-z log output on the timing options for pc3500, the stick has timing options foc pc166 and pc200 speeds. the pc4000 does not..

Eddie, you will most likely not be able to run the timings quite as tight as you tried. I benchmarked and tested a LOT of settings. The best I could do at any voltage was 2.5,3,4,8 and a burst length of 8. Those latencies tested better than 2.5,3,4,7 and were more stable. Also, 2.75v was equally, if not more, stable than 2.85v. If you can get up to 270 at 3,4,4,8, and then you can run 2.5,3,4,7 at 250, Id suggest that you test them head to head on some memory benchmarks. I'm betting based on my testing, that you can get better performance with the higher bus speed. Also, you can try slowly lowering your latencies to these settings while you are at 270mhz. Good luck, Mike.

I run my two sticks of xms 4000 at 275 FSB 2-3-3-5 rock solid stable. I have the Asus P4C-800E with 1015 BIOS. My voltage is at the board maximum 2.85V. From my experiance some memory overclocks better than other. It is hit or miss. My 9800 Pro however won't overclock at all without artifacts. Win some lose some.
