CPU-z and Bios

Recommended Posts

Hey, sorry if this in the wrong section. Anyhow, I have this RAM:




It's rated at 2-3-3-6 timings and I can set it to that in BIOS no problem. However, when set it to 2-3-3-6 in BIOS CPU-Z registers it at 2-3-3-8 which is weird. Also, I once set the timings to 2-2-2-5 but it wouldnt boot. I had to flash the CMOS and put the memory in the other slots, I have since put it back in the orginal ones. Anyhow, thanks for your support. Hope to get a professional opinion. Also, do you think I did something wrong when I tried running at 2-2-2-5? I just set to 2-2-2-5 at 1T... Is it worth another try to run it that speed, since apparently AMD 64's love fast timings.


Here are my sytem specs:


Asus Sli-Deluxe A8n

Corsair XMS 2x512mb PC3200

Evga e6800 gt PCI-E at 350/1000

Amd 3500+ Winchester at 2.2 GHZ


Btw, not that it probably makes a diifirence, I am using the newest version of CPU-Z. And I would like to save updating the BIOS or RMAing the Ram as the last steps I take. I've heard that one shouldnt update BIOS as it can cause more problems than it fixes, although I have done it on several occasions on other computers.

Hmm, thanks for the quick reply. I guess I'm going to do that. It's weird though, I assummed that if it couldnt at run 2-3-3-6 it just wouldnt POST or boot...I guess I'll update and see what happens. Also, I met setting 2-2-2-5 as an overclock, is it generally capable of running at that speed. I won't you hold you responsibleif it burns out or anything ;) Great service! Thanks.


On a diffirent note, I think I might return this memory and get some higher grade stuff to overclock this beast. I want to reach 80k+ on AM3...Do you happen to know which of the corsair models have garunteed Winbond chips? I may get the OCZ Rev 2 (I heard these baby's overclock to 260+MHz although your memory is quite impressive too) Thanks again!

Please put the memory modules on either slots 1&2 or 3&4 and make sure that you have the latest BIOS installed for your MB; load optimized/set up default, and set the following BIOS settings;

TwinX512 or TwinX1024-3200C2

Advanced CPU/Memory Configuration:

Memclock Mode: Limit

Memclock Value: 2:1 (DDR400)

Bank Interleaving: 4/Enabled

Burst Length: 8

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Active to Precharge Delay (tRAS): 6T

SDRAM Row Precharge (tRP): 3T

2T Command Rate: Disabled

Jumper Free/Frequency Voltage Control:

AI Overclock Tuner: Manual

CPU FSB Clock: 200

DDR Voltage: 2.7 Volts

All other settings should be set to default settings!Then please test them one at a time with http://www.memtest.org and let's make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!
