Please help with ram

[mike 06]

I presently have an I-7 950 Processor, Asus P6X58D-E motherboard, EVGA 580 3 gb video card, and 3X2gb mushkin redline memory sticks. I'm looking for a suggestion for a high speed ram of atleast 8gb for my system. Any fast gaming memory suggestions would be appreciated.

why 8gb?

thats a triple channel cpu so 6gb or 12gb would be the way to go

 

[mike 06]

That makes sense. Any ideas for a very fast, but stable 12gb? 3X4gb

 

[mcnumpty23]

are you overclocking the cpu?

as on that i7 overclocking the cpu also overclocks the ram

i have just upgraded my i7-920 to sandybridge and i had 6gb of 2000mhz before switching to 12gb of 1600mhz on my i7

personally i found the 1600mhz was faster because i could drop the latencies to 7-7-7

its where the overclocking comes in as your ram speed is the ram multiplier x bclk--so to run at 2000mhz you need a bclk of 200mhz x 10 ram multiplier

so depending on your bclk you may not be able to run 2000mhz anyway even if the modules are rated for it

I will not be ocing in the near future. I dont totally understand the multipliers. I'm just hoping for a good suggestion. It appears that 1600 would be a good start.

 

[mcnumpty23]

if not overclocking the cpu then 2000mhz ram would be pointless

the multipliers work like

say you can overclock to 4ghz

bclk 200mhz x cpu multiplier of 20 (turbo off) =4000mhz

ram is then set at 200mhz also as its the base clock--ram multiplier of 8 =1600mhz ram

ram multiplier of 10 would be 200mhz bclk x 10 =2000mhz ram

the ram multiplier is user selectable

if not overclocking the default bclk is 133mhz x the default cpu multiplier of 20 (turbo off) =cpu speed 2.66ghz

that gives ram speed of 133mhz x 12 (highest ram multiplier available) = 1600mhz of ram

is that any clearer?

 

[mike 06]

Yes thats better. Can you recommend a good ram? Thank you.

 

[mcnumpty23]

well theres nothing wrong with the make you already have--if another 6 gb of that is cheaper than 3 x 4gb go that way

should be fine with all 6 slots filled on your motherboard-i was still able to get to 4ghz with 6x 2gb on my i7-920

other good makes if you do want 3 x 4gb are corsair - patriot--geil--gskill

though it already seems harder to get triple channel sets most are dual or quad to fit sandybridge

 

[mike 06]

How does 7-8-7-24 1600 look? 3X4gb faster or can I do better?

 

[mcnumpty23]

those are very good latencies

what rams that?

 

[mike 06]

Mushkin enhanced redline ddr 1600

 

[mcnumpty23]

those look like the ones to go for then
