Hi, I know quite a few people have got this ram, but finding results for overclocking it seems a bit sparse, so thought it might be a good plan to keep them all together :)

Got mine last week and in the spec in my sig it doesn't seem to want to run at anything other than 5-5-5-15, Its currently at 417MHz due to the 4:5 divider from running at 3GHz. I upped the voltage to 1.9 for the ram but still it wouldn't even post at CL4. Tried running 5-4-4-12 and I got a bsod on windows loading up.

Think I saw WJA96 say he managed to get 4-4-4-12 @ 400MHz, so might try and get 400fsb and a lower multi and try my ram there.
 
I got my DS3 last night and left the timings on auto, pushed the FSB up to 428, the OcUK PC6400 2x 1GB kit was set by the BIOS to 5-6-6-20 (1:1).
I don't know enough about overclocking RAM to try and tighten those timings, but I'm not that fussed, my aim was to get the E6300 running @ 3GHz and that's what I achieved.

Edit: Hmmm.... maybe not, for some reason windows started locking up, odd because it ran ORTOS for a few hours with no problems when I first notched it up to 3GHz. I've stuck it down to 2.8GHz for now, I'll fiddle with it a bit tonight and see if I can push it up to 2.9GHz or at the very least get the timings down to match WJA96's. :(

You do know this is 2.1V RAM - it runs fine at 1.8V, but on my system to get it to perform I needed 2.1V.

Tried your 4-4-4-12 timings @ 400MHz on my system last night and it wouldn't post, is your OcUK stuff elixir branded?

Yes. But I never guaranteed it would post at those settings. I've not had any trouble with mine at all. What will it post at?

Hi,

If I was building the system I would have let it bed in a bit before overclocking it, but I do understand that you've just got it and you want to know what it will do etc.

Could you list your system specifications and what you were doing when the computer started to randomly lock up?

If you have a look in the Overclocking and Cooling Forum I have a list of steps when overclocking a DS3/DS4 that pretty much gives a foolproof 2.8GHz. Any chance we could start from those settings and tweak things in?

Every computer is different, so lets see what your system needs to get it optimised.

Can you post your MIT settings, including the RAM settings please?

Can you comfortably place your hand on the Northbridge cooler or is it very, very hot? And what are your CPU temperatures from CoreTemp?

Have you tried running Memtest?

I wouldn't rule anything out, but my initial thoughts would be something other than the RAM.

Maybe you should have bought the GeIL - or maybe not?

All I wanted to know was if it would do 3GHz, so that's why I leapt straight up to that speed. If it doesn't then it's no big deal, it's running with no problems at all @ 2.8GHz. I'm absolutely not bothered about pushing it past 3GHz, that's plenty fast for me.

WJA96 said:

Sure:
E6300
2 x 1GB OcUK PC6400 RAM
GB 965P-DS3 rev 1 (F10 BIOS)
AC Freezer 7 Pro
1 x 250GB WD SATA HDD
1 x 40GB WD SATA HDD
Soundblaster Audigy
Winfast PVR 2000 XP Expert

As for what I was doing when it locked, well there was no real pattern to it, the situations are as follows: When installing a program, when windows first booted up, when loading a game, oddly it happened mostly when I was doing nothing at all, just on the desktop. There was no pattern to the timeframe either, it happened a couple of times when windows first booted up and also there were a couple of periods where it was fine for a number of hours (during which I was installing programs and surfing the net) before it locked.

I followed that as far as the settings were concerned, I disabled all the stuff it said to disable, but obviously I jumped straight to 3GHz instead of creeping up. I'll do it all properly when I get the chance and work up from 2.8GHz.

Will do when I get home tonight.

I'll check the Northbridge tonight, TAT indicates that the chip idles at about 47c and under load (using TAT) it nudges 60c (55c under load from ORTHOS), those temps are the same at stock and at 3GHz.
I looked at my IHS when I swapped boards and the chip is a little concave, so short of lapping I'm stuck with those temps.

Not yet, I'll give it a go over the weekend though.

You're more of an expert than I am, but I figured I might of just pushed the RAM further than it was able to go, to be fair it is running at it's rated speed with no issues.

Cost was an issue, when I can afford it I'm hoping to sell on and put the money towards some crucial anniversary stuff, but it might of sold out by then.

Much appreciated!

This thread would seem to indicate that there is problem with the later BIOSes for the DS3 - even with GeIL RAM getting it to run CAS4.

Maybe my F10 BIOS is a possible cause then, is it possible to 'roll back' the BIOS?
Y'know what, now I think back, the long periods of testing @ 3GHz might of been before I used @BIOS to go up to F10. I could be mistaken though.
 
I think your CPU temperatures are fine. I think it is possible to roll back to your previous BIOS - F12 when it boots up I think and then follow the on-screen prompts.
 
Heres my BIOS settings:


I lay my hand on the Northbridge after the PC had been on a couple of hours and it's very hot, too hot to lay my hand on for more than a second or two.
RAM settings below...
 
OK - I'm very confused now! Where did the High Speed DRAM DLL feature come from and what does it do? I've not got that on my DS4's and a quick hunt around the forums seems to indicate very few people have noticed it and *** ones that have don't know what it does.

Try option 2? See if that helps. Failing that, none of your other settings seem out of line.

Must be a feature of the F10 BIOS I suppose, it says in the right hand window that it's for RAM running over 1000, if option one doesn't work then try option 2,
but my RAM is never going to get anywhere near 1000!
Ah well, I've pumped the FSB up to 414, so I'm running @ 2.9GHz now and no problems so far. I guess I'll have to wait until I get better RAM before I can get a stable 3GHz, never mind!
Any pointers on the NB? If it's hot then do I have a possible issue?
