5770 Safe Temps

[oozz77]

Hi Guys,

Can anyone running an over clocked 5770 with stock fan give me an idea what the temp range is "safe" to run in!

I'm looking at upgrading my whole system soon so I just want to push this thing to see how far it will go! I did run it at 975 core and 1300 mem but temps approached 79C.

Is that temp still OK and what are some of the overclocks and temps that others are getting?

79C is absolutly fine. Worry when you reach around 90C.

Important is to check VRM temps/memory/shader temps (try GPU-z for that). Those are the ones getting hot when you increase voltage for example.

For VRMs you want less than 100C (in games that is, dont test with furmark exclusivly).

Also, side note, but when overclocking.. push the GPU core first, until you get artifacts/driver crashes. THEN start on the memory clock. It is normal that overclocking memory can lower maximum core clock (and usually core clock is more important than memory clock)

90C = High but within the safety margin. 100C+ = danger zone.

I kept pushing this last night and got the core to 1090 and left mem at 1300 and temps hit only 82c and fan got to 82 so I am quite surprised by the overclock!!

Played a couple of games only for a short time with no problems!

Seems to have been a great card for it's time and price!!!

Here I use two 5770 in CFX and must say the heat is much more a problem since both cars run with almost no space between them (and with stock coolers is a hell inside the computer case).

But without overclock my CFX on games barely reaches 60º. With overclock (currently 970/1300 1.220v on both) the temps reaches 80~83º and on stress tests (Kombustor , Furmark , etc) sometimes get past 90º (this on the top card) the lower card is always 10º less than the top card.

So far no issues at all... and from what I know , gpus can reach near 120º (but for security reasons they all are "capped" at 100º). I say 90º is the best you can reach (with OC of course) without getting trouble.

Thanks for that guys.

Even though it is getting long in the tooth, I don't think the rest of my current system would warrant or benefit much from getting a low end 7000 series-or would it?

[Melchior]

In the majority of cases, no. Your 5770 would get a healthy boost from a faster CPU though, start saving

Indeed. Get a new cpu (sandy or ivy) and that 5770 at 1ghz+ will be newborn.

[oozz77]

Hey Danny,

Out of curiosity, why a sandy or ivy if you have a Phenom X 4 965.

Would I not then be better off until I upgrade my whole system just to get the fastest AMD CPU possible for my mobo?

Any suggestions?

[Danny Nissan]

To be honest, here in sweden in most shops they have actually stopped selling phenom IIs. There are just FX-processors to buy and i forgot that if you can go with a phenom II it might be worth it.

Problem is you motherboard only support first gen Phenoms, and those are really bad and slow (the fastest one your motherboard support runs at 2.0ghz - horrible). http://www.asus.com/Motherboards/AMD...EMH_HDMI/#CPUS

I really suggest saving until you can afford some P67 motherboard/2500K combination - these things will come down in price alot now that ivybridge is released if youre looking at saving money.

And a 2500K with a 30$ cooler (DEFINITELY get a cooler!) will overclock to at the very least 4.2GHz (4.5GHz very common) and that is simply amazing performance for the price.

Thanks Danny,

But I am an underdog loyalist and will never buy Intel.

With a good card at higher resolutions a few FPS would never make me change! We still need a healthy AMD at all costs!!

If it were not for AMD we would all still be paying $1,0000 for Pentium 4 and Intels practices over the years are abhorrent so it is AMD for me.

So sorry but what AMD based mobo and CPU should I look at with a graphics card upgrade a little later when prices drop?

[Danny Nissan]

Then i recommend getting the FX series and AM3+ motherboards

I would personally not buy anything less than the 8-core. The FX-8120 should be pretty cheap? Its a good 8-core, and will easily overclock to above 4GHz, but you do need cooling (please do NOT try to save money by not buying a CPU cooler, cannot stress this enough)!

As for motherboard, check out the following models depending on how much you want to pay;

ASUS Sabertooth 990FX (they are pretty cheap around here, dont know in your place).

Asrock 990FX extreme4.

If you want even cheaper models check out some of the M5Axxx models from ASUS (but try to get a 990FX chipset as they are high end).

Overclocking the FX-8120 is easy as its a black edition and you can simply increase the multiplier and voltage (thats only 2 settings!).

[oozz77]

Thanks Danny,

Just out of curiosity, how many PCI 16 slots- 2 or more with the 990FX boards?

[Danny Nissan]

I think most have 3 (for dual cfx its two 16x pci-e 2.0) and for three they have 16x+8x+8x but it probably depends on the boards. You have to check before buying

[oozz77]

Just to clarify, the new 990FX boards only support PCI-e 2 and not PCI-e 3?

If I were to upgrade soon I would prefer to pick up a PCI-e 3 board.

[Danny Nissan]

Correct, for PCI-E 3.0 you need intel ivy bridge or their 2011 socket (expensive).

[oozz77]

Gee Danny,

I do read many posts on this forum and I'm sure I've seen many people posting their specs with Radeon 7900 series running on their AMD systems and even pointing to reviews showing that at very high resolutions, PCI-e 3 boards showing a speed improvment over PCE-e 2.

My point here is I am sure they were running AMD mobo and CPU!!

150C is when you should start getting worried...

[oozz77]

Hi KAC,

150C is when you should start getting worried...

You are joking are you not? I can imagine possibly up to 95c but no way 150C!!

Yes, oozz77, I am joking.
