Sapphire AMD Deals

Only going by the mentioned msrps available. I know 600 is terrible. But lets face it, for the time being the 7900XT is £730ish, and the $ articles state $649, cant see a brand new product starting at £500 for a while..

could have got a 7900XT for £700 and sold the game code with it for at least £60 making it a £640 7900XT and making the GRE even a bigger joke...
 
can anybody overclock the memory on their sapphire 7900xt card? mine seems to be a dud only 40mhz before its unstable, the amd software seems to think it can overclock to 2650 but no chance its artifact city at that setting. have serious doubts about the longevity of this card have a feeling they used bottom of the barrel memory on it.

Not done any proper testing but I ran Heaven benchmark without any issues with my RAM at 2600mhz

I tend to sell my cards before the warranty runs out, so no need of a backup. Plus I can use the onboard graphics on the CPU, just to tide me over

Exactly, never seen the point of having a fairly expensive 'backup' anything!! Gfx is on cpu usually and Jeff has plenty of backups spare when absolutely required for a few weeks :D
 
Looks like the previous issue is still a problem.

While the system remains on for longer and gaming can be done for short periods (30 min - 1 hour) I am still get hard shutdowns.

So fired up some timespy benchmarks while monitoring power use, if I undervolt and power limit the card it can finish timespy, if I increase the powerlimit and undervolt or use default settings the system does a hard shutdown as it reaches 510w at the wall. The powersupply in question is a Seasonic Focus SSR 750FX which is gold rated and should easily be able to handle 550w sustained use so it really shouldn't be shutting down like it is.

Could my PSU actually be underperforming and likely have a fault (10 year warranty as its <4 years old)

My 1.5 year old RM850x was faulty so can happen.

Is that a Focus Gold Plus?

You may be having this issue:

I was worried the EVGA GQ 650 Gold PSU powering this 7900 XT would struggle but it has been faultless so far.

I even stress tested it by going for max power limit and no undervolt without issue. Though I have ended up running the 7900 XT at 1050mV with 3000 max core clock and 2700 VRAM.

It’s not the most efficient GPU but it certainly is nowhere near the worst. It is drawing about as much power as my old 3080 FE.

Seasonic have decent comms when I asked for cables etc in the past. Mail them and explain the issue. We had a mention of this in the AMD threads when I was on a vega and affected some people at the time.

If I had known about it earlier probably would have replaced it long before now. I've sent them a message so see what they say. I'd just undervolt and lower powerlimit for now, and stick to playing games with 60fps cap so it doesn't draw too much juice :)

The good news is that is not indicative of a failing or problematic GPU, it just means it’s not a good overclocker. GPUs are rated for the speeds advertised and no more. There is no evidence that poor overclocking GPUs (or CPUs) are more prone to failure. In fact my experience is that good overclocking GPUs tend to get pushed more beyond their designed speeds. So arguably they are more likely to have shorter lives.

You will be able to DSR but you must cover the cost of returns and may need to pay a restocking fee, if the item has any diminished worth to the seller. Though restocking fees are unlikely unless you have dumped boxes or damaged the item/packaging.

If you were not playing to overclock then just live with it.

If it runs fine at stock, I wouldn't worry about it, it should have been binned to meet those speeds. You could run it a bit slower to give some headroom, since I doubt you'd lose much/any performance.

it is a bit of a lemon in memory overclocking department but does seem to work fine and with a bit of fiddling about am getting decent performance from it without it sounding like a jet engine, would probably not have returned it as it met all its spec's ok.

i don't usually return stuff anyways, still im a bit naffed off the asus rog strix motherboard bit the dust when i fitted the gpu but that was probably a coincidence and will hopefully get it repaired under warranty.
