    Posted: 13 Feb 2011 at 11:08pm
Ok....was wondering something....I know that it works b/c it must with all the systems I see being configured here on DSO......How do you get 1600mhz RAM to work on the X58 mobo when the mobo only supports up to 1066 and 1333 mhz ranges.....? Havn't seen this asked anywhere...I'm just looking to expand my knowledge

I dont know where you heard that, but all the mobos cleary state 1600+ , here take a look at evga's low end board spec sheet http://www.evga.com/products/moreInfo.asp?pn=131-GT-E767-TR&family=Motherboard
 
...1066 and 1333 is old tech....my 3 year old dell uses 1333 , been even longer since ive used a pc that used 1066 lol

1066mhz and 1333mhz was the only RAM supported on early X58 boards, like the XFX X58i. That has changed now.

oh ok......I was wondering about that.....seemed kinda odd to offer a RAM speed that wasn't compatible....anyways...thanks for the answer.

no,  Max RAM speed of 1333 Mhz is what they have to say, faster speed is possible through overclocking.  The RAM speed has always been faster than that, 2,000Mhz has been possible since day one on X58

So with what you said.....Are you saying that the X58 boards don't support 1600mhz natively....You have to overclock to get it to work? Maybe a clearer explanation is needed.....I'm sure it will work...I was just wondering about the things that I had read....

Here are the specs on a high end X58 board, quote " 6 x DIMM, Max. 24 GB, DDR3 2133(O.C.)/2200(O.C.)/2000(O.C.)/1800(O.C.)/1600(O.C.)/1333/1066 Non-ECC,Un-buffered Memory"

This is how it needs to be worded, so that  non-overclocking people don't get the idea that their 930 CPU will run 2133Mhz RAM without overclocking.
 
1600Mhz is far from fast RAM, and is supported, and is not hard to get stable at all. 
It boils down to the fact that locked CPU's need to use the B clock to get higher overclocks, and changing the B clock will effect the RAM speed.
with stock CPU speeds, the maximum RAM speed will vary, depending on the motherboard and BIOS version.

if you have any more questions on RAM, or don't fully get the speed/overclocking compatibility deal, just fire away. Big%20Smile

Dont mean to hijack the thread just a ram question. If I purchase 2133mhz ram or higher can it just be enabled in the bios? Or is it complicated. Running 1600 corsair atm I dont even know if it would make a difference.

It depends. What platform are you running? X58? P55? P67? ect?  also which CPU are you running?
for the most part 2133Mhz RAM will only show small improvements, and depending on what CPU/motherboard you have, it can be a big pain in the butt to achieve, or very easy. lol

P67, 2600k at 4.3 GHZ. If its only marginal improvements then screw it lol. Just thought if I could buy ram rated at that and throw it in it might be worth it. Was easy with this ram rated at 1600 just had to enable a setting in bios.,, Completly off topic question as well Justin. My vcore I have set to 1.275 but when I run prime 95 it jumps to 1.32. Is this normal?

very small gains, would not do it, lol better off messing with the timings of you current RAM, if you want to .  still very small gains for a lot of time
 
when the CPU goes under load, the voltage decreases, or sags, so to help this out there is a thing called load line compensation or LLC, this boots the voltage up, to help with voltage sag, there are several levels of LLC on most P67 boards, so to see it raising the voltage higher, is normal, just a more aggressive LLC settings is all.
