Good afternoon all!
New to the board - 1st post. Also new to changing RAM settings so please excuse any dumb parts to this post.
Right for refrence....
I have a fairly old machine that I brought from OcUK a year or two back now probally. A quick rundown on the machine:
mobo= Asus k8v se delux (Currently running latest beta bios but have run latest stable bios with same issues) HDD1= sata maxtor 200gb. HDD2= 500gb sata WD Caviar. Ram= 2gb (2x1gb) OcUK ddr 3200 value ram (matched set). Video= AGP Sapphire x1950 pro 512mb. Processor= amd 64 3400+ (clawhammer I think).
Triple booting Vista ultimate 64bit on 500gb and WinXP and Slackware Linux 11.0 on 200gb.
Now thats out the way, I'll tell you my problem,
I have recently changed 1gb of corsair twinx 3200 memory for 2gb of OcUK value memory so that vista64 can run as it should. After vista install (when I found a working 64bit unsigned fastrack raid driver! - but thats another story) I looked at the vista rating and noticed the ram score was really low (2.1 rating). All other ratings were well over 5, except the processor at 4.1 (to be expected). I thought this strange so I checked up on a few settings and used CPU-Z to find that my ram was only running at 100mhz. Now long story short, I relalised I had been stupid so I then put the ram in the correct slots
bank 1&2 on mobo, instead of 2&3. (My mobo has 3 slots and does not support dual channel).
Now this changed my bios ram readings to read 200mhz (effective 400mhz) as it should. However, every time I boot into either distro of windows it bluescreens pretty much as soon as you login or it wont even get that far and will give various errors on bootup.
I have found that this will happen just when the ram is set to the correct speed. I can change the memory settings in the bios to any speed but 200mhz, even 5:3 DDR 333 works fine, and increased my vista memory rating score to 4.2, a big improvement on 2.1.
I would however like to have my RAM running at its full speed if possible (I dont even think my old corsair ram was running at rull speed, due to stupid incorrect slot useage).
Does anyone have any ideas? Also, I would love to know the correct ram timings for the OCuK value ram, the website and support line can only tell me its CAS3 @ 2.55v.
My mobo ram voltage is currently set to auto but has the options to change it to 2.6, 2.7 or 2.8. (I have tried 2.7 and 2.6... no joy).
The Bank interleaving, TWR, DDR Clock Delay and 2T command settings are also set to auto.
Here are the bios memory display info when the memory is set to 5:3 DDR 333..
Memory CLK: 166mhz
CAS Latency (TCL): 2.5
RAS/CAS Delay (TRCD): 3clk
Min Active RAS (TRANS): 7clk
Row Precharge Time (TRP): 3clk
RAS/RAS Delay(TTRD): 2clk
Row Cycle(TRC): 10clk
Row refresh cycle(TRFC): 12clk
Read write delay (TRWT): 3clk
Read Preamble: 6.5ns
Asynchrous Latency: 7ns
And here is the same displayed info when the memory is set to auto or forced to use 2:1 DDR400 settings (when I get problems)....
Memory CLK: 200mhz
CAS Latency (TCL): 3.0
RAS/CAS Delay (TRCD): 3clk
Min Active RAS (TRANS): 8clk
Row Precharge Time (TRP): 3clk
RAS/RAS Delay(TTRD): 2clk
Row Cycle(TRC): 11clk
Row refresh cycle(TRFC): 14clk
Read write delay (TRWT): 4clk
Read Preamble: 5.5ns
Asynchrous Latency: 7ns
I really would appricate any help or infomation as to why this is causing me troubles.
Thanks in advance!
