Tips for overclocking RAM pls

[jonathan1107]

Hi yall, I've been trying to OC this kit of 8gb (2x4gb) 1600mhz RAM.

They're Gskill Ripjaws... and here's the link for yall: http://www.newegg.ca/Product/Produc...cm_re=8gb_ripjaws_1600-_-20-231-314-_-Product

I've just managed 2 different OCs on 'em... One brings me to 1800mhz @ 9 9 9 24 timings

The other brings me to 1928mhz (I think I can reach 2000mhz) with 9 11 9 27 timings...

Now, the stock settings for this kit is 9 9 9 24 1600mhz. I've read a tech forum article that says you can get up to 2000mhz without increasing Dram voltage (which I have a hard time to believe) or get CAS7 (7 7 7 21) with the default 1600mhz speed still at the default voltage (1.5v)

Here's the article link: http://www.techpowerup.com/reviews/GSkill/F3-12800CL9D-8GBBRL_Ripjaws/

Now, in my experience... You can't really rely 100% on someone else's tests... because they don't necessarely use the same Mobo or same CPU...

In my case here are my specs (some of em):

-Mobo= Sabertooth 55i
-i7 875k OCed to 4Ghz
-Cpu is water cooled with a cheap kit (70$) a coolit ECO

I'd like you guys to give me pointers on how to achieve the best RAM oc I can get. Tell me what voltages you'd play with (up to now, I've only messed with the CPU volt, the IMC volt (which is the vtt I think) and the DRAM voltage of course)

Also, I'd like to know which would be better between 1600mhz CAS7 or 2000mhz CAS9...???

My RIG's purpose is for Gaming and I want best quality possible. I just ordered my self another Radeon 6950 to crossfire. And I'm trying to get the little extra FPS I can get from good RAM OC and CPU OC.

Here are some other questions I was asking myself:

-Is it better to have a lower Base clock to OC RAM? or higher Base clock? or it doesn't matter?

-Do SpeedStep... and full phase power options affect RAM at all?

well, rule of thumb = higher bandwidth > faster timings, and higher bandwidth + faster timings is the golden target (albeit not always reachable)

but from my own tests my recommendation to you is to get 1600MHz @ 7-7-7-20-60 if you can, should be do-able, don't be scared to add some DRAM volts if you need to if you're currently @ 1.5

bclk depends on what ram multi you can get

speedstep=does nothing for ram timings/speed


uclk give a great ram boost, i'll get a screenie of my triple-channel kit timings.... brb

yah, well your ram kit is another story ... its not 8gb and you've got 3 sticks...

I've just tested 1600mhz 9 9 9 24 vs 1928mhz 9 11 9 27 while playing Crysis... and the FPS seems about the same...

i've got 6 sticks


DRAM @ 1.65v
QPI/DRAM @ 1.45v

ram speed will not boost 3d gaming performance if thats what you want just stick with intel recommended if you don't really want help here

I'll try tighter timings on 1600mhz... But I think that will be harder with my mobo... I'll still give it a shot

Congrats, you win. The platform you are using provides plenty of bandwith for gaming and there will be very little difference with gaming as you have found out.

That RAM you linked to Newegg was $95 this morning, and now it's $71!

I know... Technology costs less and less everyday... Because they keep poppin new tech in every year now... Those sticks will be worth crap in a year lolzz

Arrr.... Can't get lower timings on that 1600mhz kit. According to the article I "linked" earlier... I should be able to, but it seems something prevents me from getting there.

It's probably my Mobo I guess...... :O(

With an Intel rig you don't need lower timings, you need frequency.

could be like that. it could from your board or the ram or both of them
