Timings

Thanks for the help Wayne it is much appreciated. I'm trying to get to grips with this and I have reread your posts many time and learned a lot. Having discussed this with a techy friend of mine - his conclusion is that the mismatched modules is my problem, and it has also been suggested here in this thread. The obvious solution is to buy 2x2GB sticks (unfortunately DDR2 prices are too high atm)

I'm pleased with 980Mhz 5-5-5-15 considering that they are mixed memory sticks.

I'm gonna wind this thread up until I buy matched pair then hopefully you will help me get the best from those. I've learned quite abit about memory - enough to make me consider carefully which mem to buy - voltage, speed and timings and also the number of sticks!

That's ok but I don't think it is the sticks holding you back . . .

I don't think your gonna have much luck with getting new memory to solve your problem, even a single 4GB(2x2GB) kit will likely hit a max speed of 980Mhz 5-5-5-15 because as I said above the problem is your approach to this overclocking thing and you are trying to do too much at once. . . . you must test the sticks with a stock system to begin with, I've told you this three times now but your not listening to me . .

If you want to waste more time and money then ignore me, if you want to save money, get your memory running at its meant to and actually understand what you are doing then I'm here! :cool:

Ok Wayne I'm gonna sort this out. It would be cool if you was around this evening so you can talk me thro this a bit.
Am gonna try the sticks seperately at stock speed - normal voltages etc...
I'll post the results here.

This was at an auto voltage of 2.3v for the Corsair and OCZ (set by the motherboard)

Thats at 2:1 as you can see the SPD for the Corsair is strange there is no mention of 533Mhz indeed it says 6400 but the sticks say 8500 (7-7-7-20@1066Mhz) is that a glitch?

With the OCZ fitted I lowered the voltage but couldnt boot into windows until 2.2v according to the bios. Ran a ram stress test for 10 mins with no probs so far

The way SPD is programmed is still a bit of a mystery to me but as you can see the two sets have completely different SPD settings which is more than likey causing the motherboard to scratch it head! :p

The Corsair sticks are defaulting to terrible timings? 6-6-6 etc? :confused:

Good work getting the sticks running at DDR2-1066, now choose a set and begin your voltage testing on them, either use a Bootable Memtest CD-Rom or if your running a 64-bit OS then use Memtest

[Auto] vDimm
[2.1] vDimm
[2.0] vDimm
1.9] vDimm etc

Keep reducing the voltage until either of the memtests produce errors. At the end of this testing session you will have worked out the voltage requirements of each set . . .
 
Each decent drop in vDimm needs a *good* testing to confirm stability, like 1-8 hours under bootable Memtest (10-20 loops) or Windows Memtest (500%-1000%) . . .

See ya in a few days! :p

P.S I would manually sort out those Corsair timings to 5-5-5-18 before testing . . . the OCZ are fine as is . . . .

Ok, I did a brief test with the OCZ and I cant boot into windows less than 2.2v and during testing got errors within minutes. The next step up is 2.3v so I'm gonna leave it overnight tonight on test and post here in the morning. I'll test the Corsairs after that.

I need help with that - I have a list of 18 settings to manually configure I'm unsure about the settings for 5-6 of them. I'll post a pic of the bios as it will make it easier for you to see my problem.

Here is a pic, the last 5 timings Im not sure of but there may be more, maybe YellowBeard can help?

Stuff changing all the settings, just get the main ones set to 5-5-5-18 :)

If just do that the system wont post. They have never been set properly - I just typed in some loose setting for the ones Im not sure about and the memory run very slow.

Can you confirm is this your memory please!
That Corsair stuff looks um . . . . extremely low grade, Cas 7 @ DDR2-1066 wtf? :eek: . . . no wonder you can't set them to 5-5-5-15
Take the Corsairs out your machine and when your sure no one is looking take them to a deserted area and bury them in a shallow grave! :cool:

Confirmed.......and confirmed........
I can set them to 5-5-5-15 but 980mhz max.

No were gonna do some overclocking and stuff using your OCZ kit, if they run DDR2-1066 at 5-5-5-18 that will be good enough for the minute! :)

After the clocking is done and your wanting a nice round 4GB then we may well have to organise you a new 4GB kit . . . but logic states that you need to get some clocking done so you know your system and chip are gonna be happy running fast memory . . . make sense? :D
 
So whats the story with the memory?

How come you have got too separate kits? . . .which did you have first etc?

Did the person selling them to you hype them up? . . or did you find them on a bus seat? :p
 
No hype - just cheap. I got the Corsairs from my old rig and bought the reapers to add in. The reapers cost me £38 delivered and the Corsairs were £25ish delivered. I wanted to save cash so just mixed them till I'm working again.

The voltage seems very high at 2.3v to get just their rated times and speed. When I buy my matched set I'll be paying close attention to the details. I never really got too concerned about it all.

Atm the OCZ passed stress test at 2.3v with 2:1 ratio (1066)
