Overlocking Problems with the HD5970

[emertX]

Hi there!

Anyone having these problems, too?

[purecain]

they were just moaning about the cards cooler really... the cores will hit 1ghz with enough voltage but you are going to need better cooling.... then the cards wont throttle down from over heating...

[emertX]

Yeah, but they throttled without OC too!

[overclocking101]

try taking the cooler off ading better tim and reseating

[emertX]

I don't have these issues, cause I don't have this card. But I want to buy one...but not with these problems!

[Dualist]

Anandtech have found it's the vrms are getting hot.....

for the money the 5970 is a very poor design.

That's a lot of TDP to be designing with. I think a simple revision of the card (better thermal solution and bundled software to control voltages) would solve the problems. Otherwise, just wait for a nice waterblock!

I have been scrolling through forums where persons actually have the cards and the have no problem. As seen in the pic below. Noob reviewers got a prototype card.

Thanks!

Hi guys.

Does anybody have problems when they try to overclock HD 5970 over 1GHz. Mine is stable on stock cooling and it hits 1Ghz without a problem at 1.24V. The problem is when i try to set ckloks like 1010 or 1020...

When i click aply it just goes back to 1000 in MSI afterburner or AMD GPU Clock tool.

Any ideas?

Tnx in advance.

That's because of the CCC limit of 1ghz on the core. Wait for a bios with higher CCC limits and flash to that one as soon as it is released to clock it higher

[01001]

Tnx for the reply.

I thought so to. I was hoping to do some real benching with FC watter block.

So for now there isn't any bios that could give me higher clocks?

[cowie]

if i do say i'm having any issues will i get bashed to crap?

this is f me hot like how much can a card take at these temps before its trash?
that has to be at or over spec for the parts

no case in a 63f room and two fans on the back one in front too

No offense, but this doesn't show the real problem this card is having. You can clock the card to whatever you want, but it seems to be throttling under load and dropping the clock speeds. I don't see a log of clock speeds under load in the first set of screens. Those VDDC's at 110c are VERY scary.

The 5970 is a huge dissapointment for overclockers unless it's watercooled.

my 4870 vrms went higher temps that 110c, 135 c to be exact, and it is still running. Incase you didnt see throttling would have caused the voltage and clocks speed to drop in the gpu-z, and afterburner shot. they look quite fine to me. vrms running hot isnt new.

[skugpezz]

oh and here is a screenshot of my 4870. which games perfectly

[cowie]

i think he meant my ss my motto is ebay for anything over 100c
yup my 127c put an end to it already,bah oh well maybe they will have a whql driver by the time it comes back from rma
the bugger would not run stock clocks stable anyway.
maybe forget the throttle and just have it shut down would b better i did not buy the cards to underclock them forget that.

The 4800 series don't have hardware throttling, it's done in software. The 5800 series is different. The 5970 has a throttling issue, period. It's been noted already by too many professional reviewers. It has nothing to do with prototype hardware, most didn't even receive actual hardware until a few days before launch. They were using retail hardware. Even AMD is blaming heat for the issue.

AMD doesn't need you to try to play damage support, the issue does exist and they're aware of it. However, the card should still perform just fine at stock clocks in normal gaming scenarios, ie...not furmark. Even mild overclocking is acceptable, just not heavy overclocking where a dual 5850 or 5870 setup would be far superior.

what do you call professional reviewers? too many? find me 5 articles or reviews that prove your claim.

The point is the Screens i posted had no throttling, and both cards are heavily overclocked with furmark running. as you can see the frequency stayed the same.

Another thing; try doing 4ghz with an i7 with stock cooling

As much as you would love for me to do all the research for you, I won't. However here's two professional sites demonstrating the problem and that's good enough for me.

I have no idea what you're talking about with a 4GHz i7. This discussion is about the Radeon 5970.

you said many , but there is only 2. Why i mentioned the i7 is because no extreme overclcok is done on stock cooling.

Sure man, why don't I provide 10 sources, or maybe 32 sources just to appease you? The bottom line is that two independant sources not linked to each other encounted the same issue. They are both highly credible sites so there's no reason to not believe them.

I'm done arguing with you about this. If you choose to remain in denial, that's your issue, not mine.

The bottom line is you are exaggerating. Only 2 websites stated this. I posted 2 different persons having good results and no issues. So which is more credible?
