I've read a few times the Ballistix 5300C3/6400C4/8500C5 are built from exactly the same components but should I go for the 8500C5 anyway for piece of mind it'll actually do 1066 guarenteed?
 
The PC5300 and PC6400 are the same.

The PC8500 is slightly higher binned.

They all should do 1066mhz, but the PC8500 is the only one guaranteed to.

But personally I would go for the PC5300.
 
That's what I was thinking as it's a big saving going for the 5300.

I'll be buying 8GB of it but I'd hate to go for it and find I really should have gone for the 8500 also I'm not even sure I should go for DDR2 as it might be worthwhile waiting a little while and go for the X48 and DDR3. :confused:
 
I probably wouldn't need to run it at 1066 but it'd be more futureproof and was also thinking DDR3 prices might come down a fair bit when X48 boards show up.
 
I'd say just get a set of the 5300 for now while memory prices are so low.

(btw the ram in my sig is a pair of 5300s and you can see how great they overclock)
 
My 5300's are almost dead now, after about 5 months. They need more volts now to boot my computer up. From new they were + .3 now they need + .6.

I called crucial, and they were aware of the problems, and offered me an exchange, which I will do on Monday.

Great memory and great aftersales.
 
I dont seem to be able to get mine over 740. Or maybe its my AMD that don't want to clock anymore. lol
Apparantly it was a memory error in Prime95. :eek:

What's your timings, and are they at 2.2v?

They should be able to do close to 3-3-3-8 at 740mhz.
 
Hmm I was getting advice from a couple other peeps on here and slackened my timings as I was determining my OC.
Theyre running 5,5,5,15 at moment. (manufacturers site states 3,3,3,12 i think) I've added 0.1v in Bios (so they default 1.8 I been told so running at 1.9v now)?

Do you suggest adding 0.4v to make it 2.2 then take the timings down? I tried reducing timings yesterday (wothout a voltage change) and it crashed in Prime - BSOD.

Please - no more stability tests. lmao ;)

Just up the voltage to 2.2v thats what they are rated for.
 
Well the Ballistix are advertised at 2.2v, so set it that.

At 2.2v they should do ~760mhz 3-3-3-12, ~1000mhz 4-4-4-12, and way higher at 5-5-5-15.

Tho probably a bit less than that for four sticks.
 
Kk, I shall do that - why are they set at 1.8 default anyhoo?
I'l try 3,3,3,12 at 2.2v and see if the stress test works. lol
Thanks for that :)
 
1.8v is the standard default DDR2 voltage. All motherboards default to it, and thus all memory needs to be able to run at it, albeit slower than the advertised speed.
 
Cool, Ive added 0.4v and its fine. Change the timings to 3,3,3,12 and the mobo gives a beep error and doesnt load windows. :(
Back at 5,5,5,15 and it boots fine.
 
Ok, thats booted this time. Now for a stress test lol. I'll do that overnight, I think.

I know this is meandering off topic now, but what difference does 5,5,5,15 to 3,3,3,12 to 4,4,4,12 actually make and mean? Apart from it being able to boot my PC I mean. lol
I've looked into RAM timings a lot but it doesnt seem terribly straight forward.

Wohoo this post makes me a Gangster and no loner a thug!
 
Well AMD systems like tight timings.

If you're going to run a stress test it would be worth your while trying 4-3-3-10.
 
I just need to make sure it's stable, and running Prime95 seems to be the way to do that. Are those timings likely to be more reliable, cos your just talking numbers to me. lol :rolleyes:
 
Well the first number is the major one. It makes most difference to stability. So I would expect 4-3-3-10 to be fine for 740mhz at 2.2v.
