Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

[Lsdmeasap]

Ahh well I only mentioned it because you did?

Do your 200mm fans move any air? I hear those are normally slower and do not much very much air, never used one myself.

[out5id3r]

do you guys have any suggested timings for this by any chance?

btw memset doesnt work on my pc , it was suggested to download cpu tweaker instead .

I am not very familiar with AMD, your best bet would be to make a new thread and then hopefully artdrivers would help you out.

He is our AMD guru and should be able to help you with your memory timings.

thanks will do that now

I think that I found one small error at the front page ( descriptions ) , not an error actually , but an confusing paraphrase.

tRW Timing: (Write To Precharge Delay)Write Recovery Time.

Stands for tWR and not tRW ... yes I got confused too .

Hi oit5id3r
Could you go into BIOS and list the PC Health Status for us to see? Here is a template you can use, or a picture will do.

PC Health Status
Hardware Thermal Control [Enabled]
Reset Case Open Status [Disabled]
Case Opened No
Vcore 1.364V
DDR3 1.5V 1.536V your memory should be at 1.8v
+3.3V 3.280V
+12V 12.048V
Current System Temperature 38ºC
Current CPU Temperature 36ºC
Current CPU FAN Speed 1962 RPM
Current SYSTEM FAN1 Speed 0 RPM
Current SYSTEM FAN2 Speed 0 RPM
Current POWER FAN Speed 0 RPM
CPU Warning Temperature [Disabled]
CPU FAN Fail Warning [Disabled]
SYSTEM FAN1 Fail Warning [Disabled]
SYSTEM FAN2 Fail Warning [Disabled]
POWER FAN Fail Warning [Disabled]
CPU Smart FAN Control [Enabled]

May I suggest if you have (CORSAIR XMS3 DHX 4GB DDR3 PC3-12800 1600Mhz Ram TW3X4G1600C9DHXNV) to set the memory voltage manually.

It would be more helpful if you could list your timings for us to see. You can use this as a template to do so. Also are you overclocking? Overclocking will change how you should loosen or tighten the memory timmings.

Hi I am using CMV4GX3M1A1333C9 on GA-P67A-UD3-B3 F4 bios.intel 2500k proccy.

I am getting BSODs if i use 1333 9-9-9-24 even if i increase dram and vtt.

So i tried 1066 xmp/auto ->8-8-8-24(automatically set) now there are no bsods but the bios is randomly setting back to 1333 9-9-9-24 in between process and getting bsod.When I go back to Bios MIT ,it is showing overclocking failed and reverted back to default settings..


I want to know the full 1066, 8-8-8-24 settings including cmd rate,trrc,t** stuff so that i can set manually instead of using auto 1066 in bios.

Please some one post the full timings :)

@eagle06
A single 4GB memory module?
How high did you increase VTT?
There's a F5a beta BIOS in the bios sticky if you wish to try.

I saw this last night and am thinking about overclocking my CPU using that guide since I have the same exact motherboard and processor.

How to Overclock the Gigabyte GA-P67A-UD4 | bit-tech.net
Please let me know how legit and safe it is. In addition, will 750w PSU support that type of overclocking.

I am a little confused on the RAM part. I am waiting for my order of 2x4GB RAM sticks:

Newegg.com - G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL8D-8GBXM

So I guess my question is, what RAM frequency, timing, and voltage do I set to compliment this particular overclocking. Do I leave the RAM at stock setting?

Thank you, I appreciate the help.
