Corsair Dominator's or RipJaw for OC?

I've read that dominators have an issue with the EVGA x58 LE board that I have, so Dominators are unfortunately out of the game 🙁

The regular dominators (1866 - 9-9-9-24) are perfectly fine with my EVGA boards. The GT 7-7-7-20 ones have the issues.
 
Hey, since I've been out of the game for a while (even the OC field) I'm guessing the i7 920's are OC'd base on the manipulation of the FSB (I think stock is 166) How is that translated as far as memory goes? does that translates to 1066? or 1333?
 
It's BClock, not FSB. Base is 133. MOBOs with a 920 installed default to an x8 (8 x 133) memory multi for 1066. However, you can select more multis depending on your BIOS. Some go as high as x14. There may be higher multis but, I have not seen them if there are.

That was an extremely isolated instance where a few C7 sets got out with the wrong SPD/XMP programming. It's solved now.

I have a C7 set and aside from my board not seeing all 6GB from cold boots (and subsequently blue screening or crashing during some random operation of Windows 7).

It does default to 7-7-7-20 though with XMP.

Logic says no. Manual settings always override profiles.

Have you tried them @1600 8-8-8-24 ?
Click to expand...

Yes - same issue. Of course I have other modules that will do 8-8-8-24 perfectly fine but the performance drop is unacceptable. I'd really like to pull 6-6-6-10. Probably need 2000MHz ram for that.

I already answered that earlier in this thread.

That would vary depending luck, skill, voltage applied, etc.

Keep in mind for your i7 920, let's say you were OCing the CPU @ 20x200.

Here are some common available RAM ratios you'd get for that:

6x = DDR3-1200 (see why we say you don't need high end RAM?)
8x = DDR3-1600
10x = DDR3-2000

With the 6x ratio, you can basically use value DDR3 & still OC the CPU like mad...no high end RAM needed really.

I personally am running 20x200 myself right now w/ RAM @ DDR3-1600 7-7-6 as my system has fits if i try to use the 10x ratio 🙁

It's very simple math.

BCLK x RAM ratio = RAM speed.

So if you are running stock you'd be @ 20x133 (2666 MHz) for the CPU.

6x = DDR3-800
8x = DDR3-1066
10x = DDR3-1333

It's not hard to understand if you read what i just explained again.
 
you said you're using 20x200 yourself right now which gives you 4000 (4GHz) but how does this relate to RAM? sorry I've never even messed with an x58 before, so there's something that's missing for me...

Does that mean there's another setting for changing ram ratio? does that mean if the multiplier is 20x, the blck is 200, you set the ram ratio @ 10x then your ram speed is DDR 2000? Meaning that I would need to drop it down to 6x and have it go to DDR3-800 so I 'll get a RAM speed of 1200?

The term "B Clock" stands for base clock. The CPU core frequency and the memory frequency are derived from this same clock and are independent of each other.

Would that matter if you're using manual settings?
Click to expand...

It shouldn't but on a few kits I saw when we initially found the issue, they would not run the rated settings manually or by SPD on a couple of MOBOs. So, we RMAd the memory for the customer and all was well. My guess was that those few odd kits had the wrong SPD completely, not just the wrong XMP profile, and some sub timing was off.
 
yeah i just saw on newegg that some guy ordered the dominators a couple of days ago (5/28/2010) and he was very unhappy with the compatibility issue had with his mobo (same mobo I have)

What MOBO do you have again? Keep in mind that a huge percentage of Newegg reviews are worse than worthless.
 
Quick Question you guys: Where can I purchase the memory that's OUTSIDE of CA? CA Tax is almost 10%, and that puts me off a little...

Rubycon, did you mean 6-6-6-20@1600? Mushkin has/had some modules that would pull that. Mine are rated 6-7-6-18@1600 and I'm know they will run 6-7-6-18 up to 1682 at least but I've never tried 6-6-6-18. They did have some that were rated 6-6-5-18@1600 but I haven't seen them available for sale for quite some time.

so how many extra fps did you get on crysis with this o/c ram? like 20%?
Click to expand...
Is that addressed towards me? If you'd like I could run some sort of canned benchmark at 6-7-6-18 vs. say...9-9-9-24. I'm guessing it wouldn't have much of an affect on something like Crysis +/- 1% maybe as it's not really cpu bound as much as GPU bound. May see some measurable differences in something like H264 encoding.
