ram speed, he first says he has p5b installed but its clearly not an intel based board.
I have tested the i680 and the RD600 and both clock memory a LOT better than i965 at this time.

Tony...you think a lot more memory will be 600MHz capable with N680 and RD600? Are you allowed to say how good the BIOS tweaking options are?
Sorry for threadjack- my 2p on the Spi times is RAM load because its a quad-core, or MHz throttling, but i`m not the expert....
First results are with a P5B Deluxe (965), the second are with a StrikerExtreme (680).Quote:

Im getting tired of seeing cherry picked results that get end users hopes up leading to them moaning openly to memory suppliers that their dimms are no good.
i975 around 1000 tops memory speed
i965 around 1100 tops memory speed
RD600 1200
i680 1200
Thats average top speeds not just one kit on one board that happen to clock really well.
Also remember, C2D in all flavours does NOT need huge memory bandwidth, what it needs is tight latency and it especially like 1T on the memory ;)
Come on, Tony :) What rock have you been hiding under :lol: ASUS P5B Deluxe WILL clock RAM @ 1200+ and there is a ton of results around here, less of 8-4-4-4.0 flavor but more of 10-5-5-5.0. One doesn't need 680i to do that, but a good pair of RAM and P5B DLX, that's all. If you paid attention recently, people have been constantly hitting in vicinity of DDR2-1200 10-5-5-5.0 on P5B Deluxe, be it with retails or evaluation kits and with various brands of DDR2. Even eva2000 has shown his evaluation OCZ VX2 to reach DDR2-1160 10-5-5-5.0 on BadAxe and I'm sure he's going to reach 1200 once he gets his P5B DLX. That DDR2-1200 seems to be no longer out of reach, at least with CAS5 and up to 2.5v. I'm not talking about ORTHOS or Memtest for Windows stability, but benchable. It still takes a "way-above-average" kit to get rock-stable 1200 8-4-4-4.0 at an acceptable voltage.
... just my :2cents: :toast:
EDIT: So far, I've seen only one person that has shown 680i with DDR2-1300 @ 2.5v, loose timmings, asynch clocking (sierra_bound) but I'd still like to see more reports and more detailed testing to see what that 1300 is really worth... I do think that 680i might be a better clocker but we just need more quality testing from people, with screenshots and comparisons.
It's pretty clear that the 556 screenshot is on P5B deluxe, no doubt intel chipsets are trhe worst for clocking memory, but getting 1200 is possible if you get a good chipset.Quote:

I saw a post on the house of help by ramguy openly saying they can not do much over 1000 on the P5WDH when a user was quoting Anandtech doing 1100 or so. This means Corsair are seeing the same results as us here at OCZ and its pretty much what I quoted above.
You all think that 10 people posting on XS means all the dimms and all the boards will do this speed...fact is they will not.
Bachus, please remember I have access to data you do not, when I quote average speeds im talking hundreds of kits, sometimes thousands.
Fair enough, i misunderstood the purpose of your post. I agree, hardly anyone will see these speeds at just 2.3v... bachus and i both run modded boards which is probably why its easier for us.Quote:

Tony, what I mean is that DDR2-1200 is not a limitation of Intel chipsets and only 680i will do that, but memory kit. ASUS P5B DLX seems to be well capable to do that. I'm not saying that every kit will do 1200 but there are quite a few out there and more than 10 :) Cases of people hitting 1100 on 975x and 1200 on 965P just confirm the fact that it's doable. What you need, is good set of RAM, enough of voltage supply and some time to mess around with it.Quote:

I'm stressing my point again - rock-stable 1200 is still very, very, very rare case, especially 8-4-4-4.0 and if you don't have 2.5v+ at your disposal. You might rather see 10-5-5-5.0 results around this speed and on at least P5B DLX.
EDIT: That is EXACTLY why (in my opinion) it's a risky business for memory vendors to sell such high-rated products (8888 or e.g. OCZ's 8800). You get bragging rights but often there is a price to pay. I can bet, that there is always a lot of people that will say they can't reach those stock speeds, for various reasons - not exactly because RAM is not capable.
XS definition of stable is not my definition of stable in most cases. 32m Pi is no where near stable IMO and as such I never quote or use it to show stability.
I say this so we both know what page I am on.
With latency tweaks i965 has a chance of running memory at 1200 100% stable, at this time the bios files do not have this code. Good kits and exceptional NB chipsets may do it but the bulk will not.
Drag racing ram is all well and good but please do not use it to show what a product will do 100% stable as that is just unfair on the consumer who is easliy lead. All memory suppliers suffer thru drag racer marketing in a bad way, all we need do is keep a level head and show average speeds and everyone will have the same expectations.
To finish (yes this is my last post on this) i680 and rd600 on the right board will do much higher dram speeds, I saw 1200 in july fully 12hrs prime stable so i have a good idea of what is coming.
I am talking to DFI hoping to get a final rev pic of the RD600 ASAP. I know its still being tuned along side the i680 board and both have been promised for release before xmas....hopefully by end of this month with luck.Quote:

Well, so far I don't see any drag racing in this thread :D Coolaler only shows stock results on 965P and 680i.
.. and yes, we're on the same page - 1200 ORTHOS stable on P5B DLX is rare (from my personal limited experience as well as from what others show here), just as I stressed earlier. Out of 9 DDR2 kits (including high end ones) I've ever messed around with for the last 4 months), only ONE is capable of 1200 8-4-4-4.0 primestable and that is @ 2.51v. Although 32M benchable 1200 I've seen on 5 of them...
Anyway, let's see if Coolaler ever updates this thread... I'm personally really interested in 680i results :) From what sierra and P11t has shown so far, x-5-5-5.0 clocks seem to be quite high on EVGA 680i but x-4-4-4.0 are not much different from P5B DLX... Let's see more :)
As a final thread-jack, i`ll add a line to the 600MHz thread as a disclaimer
Getting back to i680, it is quite the memory overclocker. I am presently testing EVGA and seeing some quite awesome results. I am more keen to see 1T performance over 1200+ as this is where C2D starts to shine.
1200+ at 1T on Intel platform? Is that even possible?
I have done 1300+ at 2T on 680i board.
1200 1T I wish LOL...900+ is where im at ;)
sweet might need to ask you for some tips as i'm getting sent a eVGA 680i + eVGA 8800GTX to play with and test out soon :)Quote:

coolaler, how noisy are those fans for the memory?
1200Mhz on a P5W DH Deluxe. Not even handpicked, just regular retail buy from Newegg and ChiefValue.
2.45vdimm and P5W DH 10th Anniversary Crucial. Initial run, I'll test it out some more with more vdimm and tighter timings.

Edit: I'm sorry if I come across as an ignorant fool, but what's the difference 1T and 2T?
