***Official GTX 670 thread***

This card is beginning to really take the ****, 45 degrees and now my "boost" clock is 1004Mhz... Seriously what the hell is that? So close to sending it back now it is more hassle than it is worth. (KFA2 EX OC)

Boost clock in what? Heaven? The boost clocks are lower in games as the card adjusts to how much power is needed, in an old game like Civ IV, my card only runs at 380 Mhz you, 810 MHz ram, but I still have over 60 FPS.

Use heaven to check for boost clocks, stability and temperatures. I'm sending mine back again now, to get the Gigabyte or Asus instead, I'll decide tomorrow after I see user results of the Asus card. The temperatures are still too much higher than they should be on the KFA2 EX OC compared to Asus / gigabyte.

Hey bhavv not sure if you'll know this answer to this but I sent a webnote today about sending backy kfa2 and I got a reply with an rma number and to send it back.... Is this the norm for dsr or have they misunderstood me and think the card is faulty?... I don't wanna get charged the rma fee as it isnt faulty I'm just in the same position as you, unhappy about temps

 

[kmax86]

I suggest phoning them up and say that you are returning it under DSR
I did this before but witout saying dsr and they classified it as RMA for faults and got
penalized.


I have feeling for some reason the 670 GB WF will go up in price

 

[PCplodder]

Look at that card, doesn't it just scream £320?

 

[Sasahara]

Guys do you think that Seasonic X660W will be ok for GTX670 SLI, with no OC.CPU is SB 2700K @ 4.6GHz, 2 SSD's, 1 HDD, Xonar and 8 GB RAM?
I know that Guru3d recommend 700W at least, but I wonder maybe i can do some tests on mine Seasonic??
Tests only.

My set up with the 670 @ 1250/6800 2600k @ 4.5Ghz running with UHeaven running so 1 core maxed peaked at 300 W from the wall. So 270 W output. Adding another 100 W for the CPU being maxed on all cores would still leave around 280 W for the 2nd card which isn't gonna use 200 W.

So yes it will be fine.

I hope not, as thats what ive decided to go for instead of the KFA2. Seems to be a cooler running card from what ive seen.

 

[~bones~]

Ok cheers, it does say unwanted under the reason for rma but I'll ring and confirm just incase, hope it goes through quickly because I think your right and the windforce will go up as stock runs low

 

[Kraven]

Anyone?

I asked the same question about 10 or so pages back and people reckoned it wouldnt be worth upgrading for the small increase.

However I think it will be a nice boost and hopefully we can sell our 580s for a decent price.

I am holding out for the Asus TOP versions.

 

[spixelspixel]

if you have no plans on getting a 2nd 580 then yeah

No, It screams £319, as the £1 pentium 2 heatsink has been removed

 

[PCplodder]

Hahaha.

I would actually love to see how much Nvidia pay for those heatsinks... I reckon its literally about £2.50

 

[shadow_boxer]

I know, the heatsinks are a complete joke. Really want to put my Gelid cooler one of them but don't know whether it'll fit!

PGI, get some custom watercooled GTX670 windforce results up please

Most scenarios to be honest, the only time I see a high core frequency is when I play tribes and that doesn't even take the GPU usage very high. Though things like furmark, 3dmark or anything that stresses it and I can see my clock going as low as 1044 :|

I've already uploaded and posted afterburner graphs of the throttling. At 80 degrees you lose 25 Mhz. If Nvidia are fine with Making such a rubbish stock cooler for this card which causes it to heat up over 80 degrees at reference speeds, why do they throttle it by 25 Mhz?

Armchair engineers are out in force I see.

Why even worry about it, it's not a problem. They've tuned the reference cards performance for speed v noise that's all. If you feel the need to adjust that then so be it.

At 80c the card drops a small amount of voltage and a tiny amount of speed so the fan doesn't need to work as hard and the card runs quieter. This is important as noise is one of the main things reviews pick up on.

One thing I can guarantee... Guys a lot smarter than you will have tuned the stock cards.

 

[bhavv]

Furmark will heavily throttle these cards for safety, don't use that. Heaven is working for checking maximum clocks, stability and temps.

This GPU boost is nothing but an undesirable virus for overclockers, with an implementation of thermal throttles from a stupidly low temperature like 70 degrees.

Yes it is a problem when trying to overclock these cards to their highest safe limit. The Gigabyte can do 1250ish Mhz and remain under 60 degrees without touching the fan so it won't throttle at all. Why should I pay for a card that is running at default speeds and temperature that cause the out of the box overclock to throttle due to not remaining below the thermal limits set by Nvidia?

Its not even an engineering issue, its purely software, and the GPU boost feature is really nothing more than an undesirable virus that can be disabled.

 

[Cuchulainn]

The noise of the stock cooler, sitting at idle, is really, really bugging me.

First thing in the morning I promise. Aiming to get up around 6am (on a day off I might add ). Get the kitchen cleaned up so I can fit an 800D in it and get cracking, provided I don't spend 3 hours smoking and looking at my rig thinking 'why the hell do I bother, what an effort' I should have some tests done by late morning. The block will be seated with MX4, also thermal pads on quite a few parts that even the windforce doesn't touch (mostly vrm's)

Two main tests I will be doing under water, over 1359 on a heaven run, at the moment I near enough get instant driver failure above that clock. Second test will be to see if the clocks will raise over 1370 in Batman AC, at the moment anything over forces the card back to stock boost (1189).

Teaser pic for ya

Looking good, look forward to results. I've hit almost the exact same wall as you with regard to core OC. Will be interesting to see if the block helps as on air I wasn't getting above 54C even at 1360.
