4 GB Memory suggestions.

slipd · 3 May 2008 at 16:40

Hey guys,

I'm getting random bsod atm with my ram the most likely culprit… I only recently bought a second set of 5300 Crucial Ballistix and no mater what settings I use (currently on default) I still seem to get these random freezes and bsod. Testing both kits in different configs and on their own, their fine – but as soon as you put them together I get problems.

I've just turned off 'restart after system failure' in the hopes of getting a better glimpse of the actual MS error code.

In the mean time I'm after your 4 GB kit recommendations? I don't go mad with my overclocking, but I would to be able to get my E8400 back to 4 GB again with 4 GB of ram

Currently using a P35 Gigabyte board so they need to be compatible, and ideally, I don’t want them to cost a fortune in case I upgrade to a drr3 system within the next year or so?

Cheers!

Probably the G.Skill PC6400 PK. It should do the 900mhz that you'll need for 4ghz.

Corsair pc6400 4-4-4-12 only £2 more than the 5-5-5-18 corsair memory but ocuk not selling it yet............ :confused:

Hey guys,

Sorry to dig up this thread again, but I still haven't got round to upgrading my memory...

I just checked back, and it seems that the link given to me by Cob doesn't work anymore

So what 4 GB kit should I go after now?

Cheers,

SW.

My vote is still the corsair 4-4-4-12 6400 2 x 2gb kit.

I have mine running at 5-5-5-12 at 1066Mhz atm and I have still yet to get round to tweaking the timings to see if it will do even better yet.

Good warranty and nobody currently reporting problems unlike the crucial stuff.

Cob · 18 May 2008 at 12:53

The OCZ DDR2 PC2-8000 Platinum XTC 4gb kit is the best value for money 4gb kit around atm. It's the exact same as the 4gb OCZ PC2-8000 ReaperX HPC kit but with different heatsinks and is a lot cheaper, but OcUK don't sell it so I can't link to it.

Otherwise the G.Skill 4gb PQ kit is worth a look.

Is that the XMS2 stuff that can be found on some sites, going for about £74?

I used to have Corsair stuff in my old AMD rig and it was faultless

That's the one with the nice heatsinks. I found mine for £70 plus postage. Still don't understand why ocuk aren't selling them.

I had corsair xms for 5 years in my amd rig as well which was partly the reason I went with them with my new Intel rig.

Can't see the point in spending another £12 for 8000 memory when the corsair (or even other good brand makes) will run at 900 @ 4-4-4-12 and 1000 at better timings than the ocz. I;m not saying the ocz won't do 1000 at better timings than it's stock but what are you paying the £12 for?

slipd · 18 May 2008 at 14:14

These ones:

Ordering now!

My Ballistrix will be on the Bay later

I don't see the point in paying £70 for PC6400 Corsair when the PC8000 OCZ can be had for less than that.

I did look, but I couldn't find it anywhere?

I've ordered now anyway :rolleyes:

Ahh I was using ocuk prices and didn't think to look elsewhere

And Sam, you won't be disappointed by the corsair. Just remember to put 2.1v through them (or more if you want to max out your overclock)to get 4-4-4-12 at 800+ speeds.

will the OCZ do 4-4-4-12 @ 400mhz?

tossing up between them and the corsair greebo has pointed out as i've just RMA'd a set of ballistix and want to move to 2x2gb (maybe 4x2gb) instead of 4x1 to avoid the ballistix merry go round of death.

I've let my new ram settle down and today I decided it was time to see what they could do

I've set them to 4, 4, 4, 12 @2.1v but I can't get my overclock any higher than 400 - if I set it any higher my system simply fails to boot...

My old Ballistix used to be able to do 890 to get my e8400 to 4 GHz but these sticks seem to have me stuck at 800? What am I doing wrong

Greebo · 22 May 2008 at 17:49

You tried putting a little bit more voltage through your nb?

Yeah - good call!

They're all at stock atm...

SW.

slipd · 22 May 2008 at 19:03

Nope - it's having none of it

I think I might try dropping the multiplier?

SW.

slipd · 23 May 2008 at 10:52

I've been reading a few reviews of these sticks that all seem to say thay using 2.3v is the only way to get any sort of OC out of this ram?

When I get home I think thats the first thing I'm going to try

SW.

PS. Is 2.3v actually safe with these sticks? Just read that 2.1v is the recommended max...

Greebo · 23 May 2008 at 11:45

Hmm, I just slackened off the timings straight away since I knew I was going to overclock the ram far past what it could run at 4-4-4-12.

I put them straight on 5-5-5-15 and left at 2.1v and it runs fine at 1066.

Perhaps before upping voltage, you might want to try slacker timings and see what they get up to.

Looking at overclock3d.net review even with 2.3v you will only get to 883 and not the 890 you need.

So your choice is looking at either 2.3v and hope that with your chips 890 is stable or at least 883 which will give you 3.973Ghz on your cpu or leave voltage at 2.1v and run slacker timings, fsb at 445 and 5:6 ratio giving your memory 1068, which if like mine, should be fine and stable.

You might want to run some tests to see which is better performance:

890 @ 4-4-4-12 or 1068 @ 5-5-5-12 but as an educated guess the memory running at slacker timings at 1068 will be quicker.

Personally if you get both settings stable I would be tempted to go for the slacker timings if it meant only putting 2.1v through them 24/7 even if there was no performance gain to be had.

Best of luck

They seem to suggest the memory doesn't like high voltages - confusing
