[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 767

post #7661 of 38701
So just wanted to report in on some progress i have been making with my Xfire 7970s, i think i may have found my limit on the core for these guys in Xfire, being 1.250 keep crashing at 1260 but havent fed them more voltage than what 1.250ghz requires (1262mV).

Although i am quite impressed with how well the memory is clocking!!! I have my memory up to 1675 currently and going up in 50mhz jumps, i have almost broke a 17k P score with my processor just at 4.5ghz....I can almost bet that i will get over 18k or close to it with my processor at 5.1ghz (sadly this is my 2600Ks limit) i did not expect the memory to clock this well!!! Once i find the memory limit im gonna throw my 5.1ghz OC at it and see what score i will get!! Will keep you guys updated!

Haven't had this much fun benching in a while!

EDIT: Temps have not broken 44c...... <3 <3

EDIT#2: Anyone know why 3DM11 sometimes doesnt record my GPU core clock correctly? It shows 300mhz a lot for some reason, although my scores clearly reflect that my core clock is not 300mhz on the gpu lol....

I did a lot of research when buying mine and opted for EK in the end. The VRM cooling was important to me.

Well will the regular EK Acetal blocks work properly, and cool the VRM's well? It's $105 on jab tech. I like that block, and I like the price. smile.gif Actually, I like jab tech's prices in general. I think there was only the CPU block that was cheaper elsewhere. Only other thing was the rads, but they weren't cheaper elsewhere....its just that jab tech didn't have any stock. frown.gif

Still confused why PPCs isn't fine?

On a different note, if anyone was interested. I installed the 8.960.0 (12.4 beta or whatever) over the 12.3 preview (with RC11 file patch). The F@H scores don't change at all even with OpenCL 1.2 frown.gif

Because jab tech is cheaper?

I did notice that PPC's has the Raystorm CPU block for cheaper, AND they have the XSPC radiators in stock. So that's nice, and I might shop there for those parts. I'm trying to find the cheapest possible prices on everything shipped. jab tech has it...EXCEPT they don't have the radiators in stock right now. ;( Since I had a $16 shipping charge at PPC's anyway for the rads, figured an extra dollar to ship the Raystorm wouldn't be too bad, considering I'd be saving $7 by ordering it there.

Yes, everyone here is very helpful.

I've had problems with mine and everyone was very helpful in trying to help and very responsive. Though, following this thread and other threads, I was sure you were going to get a 680 instead.

I just wanted to make sure it had been considered since it wasn't mentioned before smile.gif

The whole cost comparison is really difficult due to the high shipping prices these companies come up with. I would recommend EK's online shop if you were getting more than 1 block as they cost ~$20 less direct because of VAT, but the shipping is extremely high (Slovenia to US via DHL = holy crap. I paid $65 shipping for 3 blocks :O)

I've been figuring shipping costs into everything. Since I need rads anyway, the cheapest is PPC's for rads, but shipping is $16 alone there. eek.gif At jab tech for both blocks, tubing, and 8 Yate Loon fans, shipping is $7 (only $11 with two rads and the rest of that stuff)...but they don't have the XSPC rads in stock. frown.gif However the CPU block is $7 cheaper at PPC....and only adds $1 onto shipping (saving $6 there).

I dunno...I'm watching all my prices everywhere, and trying to make sure I get the best deal possible.

I'm at $307 and some change right now for everything for my entire loop, plus the shipping to get my pump, res, and fittings here from Australia (which shouldn't be TOO expensive).

Wow this thread moves fast. Really interested in getting a high overclocking HD 7970. 1300Mhz on the core is a 40% overclock for 7970 while most GTX 680s max at 150-175mhz overclock.

Two MSI 7970 Lightnings right? Have you tried maxing the voltage to 1.3V? Whats the fanspeed for both cards and what is your ambient temperature like?
