Question About Sapphire HD5770 in my case ;o - Page 6

post #51 of 59
TBH I do not think it is the power supply, how many amps are you getting on the 12v rails?

Isn't techsolo a decent reputable dutch company? They just aren't very popular out of the netherlands is all. IIRC they also offer 3 years warranty.

If it's unstable at 925/1300 you may need to up the voltage, check your load temps at 900/1300 (stable). The max you wanna be hitting is around 90, if it's below this then you can up your voltage. You may be able to do this in MSI afterburner, IIRC there are 2 versions of the sapphire 5770 (one allowed software modded voltages, the other did not).

The card is running great at stock. OP, give it some time and when u can get a new power supply.

Enjoy your card, its an execellent addition to your system.
I would bet that much of the money spent on that system is their money, so if that's true, then it's their investment.

Even if he had a generic 850W, it still wouldn't mean anything because overclocking anything dramatically increases the need for the power supply to deliver clean and stable power.

Yeah but what he said was the OP may have a non-ref 5770 or a "locked" 5770 which means he can't up the voltages.

OP why are you bothering to OC that GPU? You won't notice much if any difference, maybe 2-4 FPS. IMO it isn't worth it.

Play with the rest of the system before you go the GPU route.

He asked him how many amps he's getting from that PSU's +12V. So I'm saying that it's not about that; it's about the PSU's ability to deliver clean and stable power. Yes of course it also needs to have enough power, but it's more important to have a PSU that delivers the cleanest and most stable power possible for the sake of keeping an overclocked system stable. That is, as long as the PSU has enough power.

True. Although I don't think his PSU will benefit any overclock, his GPU may still be a limited one.

I said this just to make sure the PSU was delivering enough power.

I did say that IIRC techsolo is a decent dutch manufactor and so the PSU would be capable of delivering stable and clean power unlike some no-name PSUs.

Regardless 5750 overclocked by just 100-200/100-200 would barely change power requirements and so it is highly unlikely that the PSU is the problem.

In fact there is nothing wrong with that overclock, a lot of these chips (Juniper) max at around 900/1300 on stock volts.

Just increase the volts if you want a higher overclock but make sure the temps are ok.

Fair enough.

battleaxe231: can you post a picture of the specifications label on the PSU?

Thank you very much Spct, and other fellow members of OCN.

Sometimes when i zoom in with my scope on Black Ops i see some black strange lines on objects (its hard to explain) but when i zoom out its gone. I also played Just Cause 2 maxed with vsync off, but the same strange lines appeared. But what also VERY strange is that when i play Crysis 2 at max quality it runs smooth and without any strange lines on textures.

Im really thinking it comes too short on watt and quality. Because my psu is not very great quality but it has 6-pin tho. I think i need a new one

Ok, i will open up my case and take a picture.

EDIT: and b.t.w, i also earn my own money with paper-rounds, so its 1/2 investmend of my parents and myself.
