Gskill ripjaws 8gb 1600 (2x4g) question

post #1 of 7
Thread Starter 
My friend keeps talking about changing the timing or something to help my memory. What is he talking about? And if it helps how to i change it on my asus m4a89td motherboard in bios? What do you recommend is a good timing?

Refer to this article: http://www.overclock.net/faqs/26706-...s-dummies.html

There should be some type of Memory or DRAM settings in your BIOS (never had an ASUS board) and you'll see the different timings that you can change. Make sure you understand exactly what you are doing though before you go messing with it.

Find out which model(for stock latency values) you have from newegg and post the link here. The optimization will depend upon your stock settings.

I'd just ignore your friend cuz it'll take a bit of time and plenty of lockups in the process for what's really not much gain at all.

Let me start by telling you this, if you lower your latency values you will hardly see any performance benefit while doing common stuff with your pc. If this is supported by a good amount of cpu oc, then you will see a gain in video encoding/decoding precesses. Games will generate the same fps though as before. However, you will find a significant rise in benchmark scores, specially memory benches (latency value).

That being said, get the following softwares from net, they are free. CPUZ, MAXMEM preview, prime95 and coretemp.
First run cpuz and find out if the ram is running at 1600MHz or not (from the memory tab) because they have a tendency to run at 1333MHz by default. If not, then go to bios memory speed setting and manually input/select 1600MHz. Now open advanced memory setting/timings in bios and try these values CL-8 tRCD-8 tRP-8 (all of these default at 9) tRAS-24 CR-1T. press F10 to save and restart pc. If it boots up, then run prime95 and start blend test to see if the threads run ok. If any of the threads stop or pc crashes then the oc is not stable. In such a case try to keep the tRCD at 9 and CR at 2T in that order. If everything runs fine then you can push for even tighter timings by lower the cas values one step at a time. If you are a beginner then I would advice against that because that step might require a push in dram voltage. Luckily for you, your ram is rated at only 1.5V so you have quite a bit headroom there, but you might not be mentally prepared to alter voltage settings at the very first go.

At best you will get 7-9-7.
