Best 2GB Kit for OC'ing

[smids]

woh there smidsy!

I had 2gb of the zx (still have incedentally) and it wouldn't go past 245 with any timings let alone the tighter ones (I think I gave up at about 3-4-4-8 or similar and vs up to 2.95) I ended up buying the hz because it came back into stock and they're sitting happy at stock timings and volts at 261 (3-4-3-7 I believe).

The 2.5 CAS time above I think is misleading anyway and the on board mem controller can't do halves so despite what it says in the bios it will actually be running at CAS 3.

Finally.. I thought the debate had landed on A64s liking bus speed over timings? I was under the impression timings were a socket A/maybe 754 issue? But not with the on board controller??

No, angry games did a whole test on this. Timings were more important than frequency. Which is why say 200mhz RAM (divided @ 2-2-2-5 1T on an FX is really no different to say 250mhz (3-3-3-8 for example x 12). Bandwidth is needed by intels because iirc, the bus has to carry info from the chipset to the cpu for the memory controller (in a very simplified way). A64's onboard requires less bus, it being on the cpu die.

CAS2.5 is supported by the memory controller (CAS1.5 isn't). CPU multi's don't work on halves, is that what you are thinking? TBH, I wanted to run 200mhz mem anyway @ 2-2-2-5 1T.

So is the ZX still the way forward then?

 

[Bito]

Any body tried the G.Skill HX's ??

I will let you know tonight . Still reading up!

@Bito: Don't bother. Read Xtremesystems for why.

Dont take too long I need to order this weekend!

I phoned up Crucial today to get a refund on my 2nd set of Ballistix today. The woman who answered did not want to give me a refund at first, but send me out another set of Ballistix
She tried to give me some old waffle that they only do refunds for orders that are not more than 30 days old. Yeah right.
After a bit of moaning, she spoke to her supervisor and he said that they would refund me £260 in the end. I even managed to get them to refund me the costs for sending it RMSD back them too!

Well Crucial seem to ok with there RMa service. Well im sure they have had a lot of time to sort it out with the anount RMA's they have had on there "GB sets

They are in hand still. Gonna be up for sale soon though, along with 2 74gb raptors .

Anyway, I have been doing some research. You know scoobie, everyone seems to think these Samsung UCCC and BP PCB's are the bee's knees (the HZ) so I might just stick with them. I run at 250mhz anyway and will just get tightening on the timings. 3-3-3-7 1T should be fine + I can then go further.

One thing I noted though, I tried to flash to 623-3 for these 1GB sticks and comp wouldn't boot with them in (worked when I put my GeIL's back in). I then flashed to 623-2 again (my original BIOS) and it booted with the 2GB in. Something to note.

Scoobie - I'm at a loss here. I honestly don't know. Im gonna do some more reaearch tonight and will get back to you. It might be worth noting that these HZ's are one of the 4 recommended RAM kits in the memory FAQ. Obviously they are quite good then! Those ZX's are of unknown IC's too, and we know the quality of these HZ's.

Can the HZ's run 2-2-2-5 200HTT as well?

 

[smids]

No. kimandsally got them to 2.5-3-3-6 1T though.

 

[Scoobie Dave]

What do you think of the Corsair 2GB DDR XMS3500LL Pro TwinX (2x1GB) kit?

Is it worth getting over the GSkill?

 

[man_from_uncle]

On paper the Corsair is slightly ahead, though maybe not enough to justify the price difference. If money was no object though the only reason i'd steer clear of the Corsair is if i was using a DFI board. I've now heard of several people on this board use Corsair for some serious overclocking with DFIs without a problem, but the DFI-street boards are littered with people who have counter examples.

But as I am using an Asus premium my 3500LLs are pulling great times.

 

[man_from_uncle]

I've just seen the prices of the 3500LLs now and they are a lot more than when i paid. I'd go for the G.Skill and save yourself 90 quid.

 

[Scoobie Dave]

Might as well go for some G.Skill then. I did think the Corsair was a little overpriced for what is was.

Hows the memory going? Still not sure what to get HZ or ZX. . .

I really don't know Scoobie tbh. It depends on your usage. What do you use your PC for?

Also, it depends on what you use for dividers etc. I don't need more than 250mhz (the base rated speed of the HZ). If you need more, get the HZ. I'm not sure if my ZX will do 250 but I'm putting it on a 166 divider (to run 2-3-2-5 1T @ 208mhz). That's my personal choice. Look at Xtremesystems to help you choose though, they have HUGE threads on this.

I use my rig for gaming mainly m8. Have you tried running your ram @ 2-2-2-5?

If I get the ZX I would run it 250HTT x11 with a 183 Divider = 211HTT for the memory. Would be lovely if it would run with 2-2-2-5 timings.

Yup. It didn't like it. However I have not tweaked or anything. About 5 errors per pass memtest so it is doable. However, it's running 208mhz 2-3-2-5 1T fine. Weird. TBH TRCD makes little difference though.

Have you tried upping the voltage?

 

[smids]

Have you tried upping the voltage?

Nope. Been a bit busy tonight! . I have a nice 120mm 2400rpm over it too (having just come from BH5 @ 250mhz and 3.5v) so I'll know soon enough whether it will go. I'm think I made the right choice with this stuff...but off for a quick game 'test' now .
