How many was that 10? 20 pairs?
Maybe its my chipset that won't do anymore, but im pretty sure its the mem...

He said they're building 5+ systems a week for delivery to customers, all pre-overclocked and all using this RAM at 920MHz in an Abit AW9-Max

It's a very interesting thread as Gibbo says he did 1100MHz with this RAM at 1:1 but then later admits the motherboard he was using has a maximum FSB of 475 so it would appear it couldn't have done 1100 as 475 is only 950 at 1:1

Have raised MCH voltage to 1.7v and ram to2.3v. Now stable at 458(916) @ 5-5-5-15. FSB at 367.
With 1:1 ram divider I can get to 377 FSB with [email protected], MCH 1.85 and CPU 1.48. Cant get 380 to post with 1.9 MCh and 1.5 CPU !!

i have this ram, its a bit rubbish for overclocking.
i can get 480fsb x7, with the ram set to 2.0 on an s3 which is the same as a ds3 without extra capacitators.
any attempt to increase ram speed, i have to do bios battery uninstall, which, on my motherboard, cos of the iceq cooler on the gfx card, means taking out the soundcard and the graphics card just to get to the battery or the jumper
im going to get better ram at some point tbh.
you dont need more than 3ghz anyway tbhwy, ive found no speed increase at 3.2ghz over 3ghz on anything so far.
edit: whats MCH ? i left that on standard voltage, along with my ram voltage (1.8v) when i hit 3250 stable mhz!!!

Given that you got a 20% overclock that's a bit of a daft statement isn't it? Have you tried loosening the timings?
eracer2006 said:
The RAM is rated at 2.1V, so you're doing well to get any overclock at all. You may need to run these at 2.3V with active cooling to get over 500MHz FSB.
480x7 (3.36GHz) is one of the top air overclocks so far achieved on an E6300 so I'd be flashing my validated CPUz report rather than slagging off the RAM that helped me get it!
The DS has the same number of capacitors, they are a different make is all.

That's hardly the fault of the RAM though is it?

Make a note of my e-mail address, I'll buy your very overclockable GeIL at a decent price when you go for 'better' RAM!
eracer2006 said:
SuperPi shows no improvement? I doubt that. What you mean is that your computer is limted by the graphics card in games so you haven't noticed the speed increase. It's there, it's just not so obvious as the first 1200MHz increase!

It's the Northbridge voltage adjustment. It seemed to be very important with the BIOS's before F5, now it doesn't seem to make such a big difference, except it does increase the heat in the case, so I'd be tempted to try it and if it doesn't help, put it back to [NORMAL].
If you haven't realized it by now you've got a cracking CPU and potentially excellent RAM. You're hitting 3.36GHz on a chip rated at 1.86GHz. That's an 80% overclock! On air. Give the RAM an extra 0.1V (2.1V) and try again. If that doesn't help try again with an extra +0.2V (2.2V). It could be that your air cooler can't cope with such a massively overclocked E6300.

I don't think that's true. Gibbo has repeatedly stated that this GeIL PC6400 Ultra is good for well over it's rated speeds, albeit at slacker timings.
What the OP is complaining of, is an inability to get anywhere remotely close to the 1100MHz/550FSB that Gibbo says they have been known to do.

Hi there
The GeIL 2GB and 1GB PC2-6400 CAS 4-4-4-12 Kits are your best bet now. They can run at PC8500+ speeds at CAS 4-4-4-12 with ease and I've personally had a pair upto 1150MHz stable at CAS 4-4-4-12. Whats even more impressive is one of these 2GB Kits will only cost you £110+VAT!
Nothing can beat these kits when it comes to value for money and you will also find it hard to buy a better overclocking kit for more money as well, these really are the dogs danglies.
The code you want to be buying is MY-058-GL !!!!
I still think anyone getting 450MHz+ at 5-5-5-15 shouldn't be complaining when the stuff is sold on 400MHz 4-4-4-12 anyway.

Geil stuff is ok for moderate overclocks... but most of the reviews top out at 940 @ 5-5-5-15 which isn't exactly earth shattering... just annoys me when I see people complaining they won't do amazing overclocks because they've bought the wrong ram if thats what they want...
my PC2-6400 HZ kit does 1002 @ 4-4-4-12 on stock voltage and thats not even sweating it, with 2.4v they will do 1200 with 4-4-4-15 100% stable, but they get a tad warm for my liking even with active cooling at 2.4v.

I cannot get my geil 6400 above 425-430mhz no matter what I try, and believe me I've tried everything suggested by the guys here. I also had to rma my first set (wouldn't run at stock speed).
The disparity between what some ppl are getting on set ups similar to mine suggests to me that some of the geil memory ppl buy are from different batches, parts of batches, etc, thus giving different results. Don't get me wrong, the geil runs fine at stock, or slightly over, but I bought this stuff to overclock, not run at stock.
Please don't suggest that I, or a lot of other ppl aren't doing it right, (though that might be that case), when you try everything suggested here, then it makes you wonder.

I don't think anyone would suggest that you're doing anything wrong. I think you've got some of the less good stuff. I just have to wonder how come the OcUK technicians never have any that won't do 460MHz at 4-4-4-12?
I have to say I haven't spoken to anyone who can get that speed with those timings.

Hi guys....sorry pieman109 that your geil arn't to good but here's some proof that there are some good un's out there.....this is mine @ 1000 1:1 C4....and most they did was 1020 1:1 C5 2.35vdimm.

Could be the fact I'm using a DS3 with the F7 bios versh. Saying that, I've seen 900mhz memory speeds with this combo. I'm tempted to chop this mobo in for an Asus which apparently will allow me with run with a divider below "x2" if I can't get the memory above 425mhz.
I'm still happy with the performance so far though, blows my old S/D 3700 @ 2.6ghz totally out of the water.

vocch said:Do you have any screenshot's of them doing 1200?....can't complain about my Geil got them cheap and they have reached 1100.
don't have I'm afraid... and I'm not planning on messing with my settings atm as they are stable at 1002 on stock voltage... but heres a thread where someone messed with the same RAM:
http://www.xtremesystems.org/forums/showthread.php?t=102595
He only gets to 1140 @ 4-4-4-8 but he was going for the lowest latency not the highest bus speed... loosen the timings a bit and they will do 1200 - possibly more with the right settings - but theres a wall on most motherboards afaik at about 590-600.
Hmm didn't realise 1200 is a record...

same board as mine, but not so good RAM, hitting 1170...
I'd go for it again but as you'd see from my old forum posts here I killed my first Inf 975X and E6600 playing with RAM settings.

I thought my geil 2gb 6400 ram wouldnt go past 460mhz (which is ok) at 5-5-5-15 with 2.1v. However then i realised it was my mobo that was limiting (which i dont think some people might realise is the problem). So i whacked up the (MCH) and (FSB) voltage in bios to +0.35 and +0.25 respectively and now have my ram running at 486mhz 5-5-5-15 with 2.225v. Stretching my 6300 to 3.4ghz
DS4 mobo with F7 bios for the record.

Not sure if that is the case with mine, as I have actually ran it with the FSB lower than it is now (and its stable now), but with a higher ram multiplier to get 950 etc... on the ram and it didnt seem to want to play ball...
Might have a play over X-mas with it and see what I can do tho... I got some Vantec active chipset cooler from an Nforce3 board (I think) that seems itll fit, might give that a go on the NB and then whack the MCH up etc...
