**WANT 8GB 2400MHz FOR AS LITTLE AS £59.99 Inc. VAT? - THEN CHECK THIS THREAD OUT!!** (MV-3V4G3D/US)

does seem strange,if hes using the same bios and can clock to 2133mhz then you two should be able too,could have a poor clocking batch? idk,how far did you push dram voltages? i have to use 1.6250v to pass super pi 32m test,i leave imc voltage at stock 1.05v

ive seen another user with same board as me z68 v pro but with a 2700k not 2600k and he uses 1.55v for same speed/timings so it does vary in how much dram voltage is needed ect
 
Physical installation ruled out.
CPU and RAM have all been out and had a blast of air.

As I have two packs of ram rather than the single pack of four, I have installed the ram as such that one set is in one colour slots and the other set in the other, as I originally installed them prior to moving them round yesterday.

I impatiently await a new bios, beta or otherwise! :)
 
Yeah... I'm on a different model board from those guys.

I picked up the GD55 (they're using GD65) as I wanted the extra PCI-Ex lanes.

I pushed the ram voltage all the way up to 1.65V.

If it was a batch speed limitation... I would expect to see both 2 and 4 sticks max out at 1800MHz... so I'm hoping for a new bios update.

MSI's beta release notes seem inundated with memory compatability patches... so that makes me hopeful too :)

There is no single pack of four... it's just OCUK advertise it as a 16GB pack... take a look at the bottom of the advert and you'll see it's 2x 8GB packs :)

I got the same... I ordered the 16GB for this + 8GB for HTPC... 3x 8GB turned up :)

I have these in my x58 system.

2.1ghz 28,10,10,9 1.5v. 1.4v QPI.

rock solid.

Nice results, but I have to remember that ram overclocking on X58 is dependant on each individual CPU, and if I cant hit 2000 Mhz with 2133 Mhz rated 2 Gb modules, I'd be wasting my time and money trying these 4 Gb sticks out :(
 
Now that I got 3930K in my system and running, currently at 2133 10-10-10-28-1t at 1.465V.

Thats just a first stab and not tried tweaking to higher speed/tighter timings/lower voltage yet. Not sure I can be bothered mucking about with it today though. Might just see how low can take voltage at that.

Well, as still trying to lower temps on system, though I may as well try lower on memory

With with settings in quote, have now dropped to 1.425V

Tried 1.405V but got error. Seems good on 1.425V.

Don't see much point in any further tweaking.
 
Excuse my lack of knowledge! Mine runs the loop at 7m39s and its only set to 1866mhz with 9-9-9-28-2T, how come the memory set faster is slower? Does the CPU have an effect on SuperPI?
 
Thanks. I am sure 2666+ is possible for sure. I posted at that no problem but it was late by then so I did not have time to test further. Once I get 2666 stable I will post up the mem tweak it settings for MVG users.

Yes a massive effect my benching 32mb settings with CPU at 6ghz and memory GSkill Trident at tuned 2825mhz give a time of 5min 16 sec ish. This is with CPU at stock (Not evan sure I had Turbo on) which is how you should test memory as the CPU overclock then cant effect the stability of the RAM and any instability is caused by the RAM its self.

Try it yourself overclock your CPU and test 32mb then back to stock and see the differences.
 
Ah ok that makes sense :) I had my 3770k oc'd to 4400 and ran the loop with stock settings of 1600 and it ran in about 8:40, then upped to 1866 and it dropped by about a minute! New to memory overclocking though, had some trouble getting past POST by going higher than 1866.....
 
ASRock Z77 Extreme6 at the moment its on 9-9-9-28 2T and 1.40v.
Tried some of the settings in the initial post in this thread but it was having none of it!!

Here are my initial results after a couple of mins tweaking.

DDR2600 Stable on ASUS MVG

Click to expand...
Nice scores. That MVG is a great mobo to extract high memory frequencies. Many of the super high ram posts I have read have been aided by an MVG. It could go down as one of the great mobos.

Up DRAM voltage to 1.60v, This can of course come down as you test for stability. VCCIO to 1.2 again can come down. memory 9-10-10-25 1T and try again. I can also remember some subs from last night if these help I will tell em you. Just see how you go on with this for a start.

Yes its a great Board I can get my GSkill Trident to DDR3065 on it. I run the Trident Tight at DDR2825 and CPU at 6ghz for benching. Amazing stability.

Cheers I'll give it a go - be happy to get to 2133 for 24x7 :)
