MSI GeForce GTX 670 OC Twin Frozr PE

As there doesn't seem to be much mentioned about this card in the forum yet, I thought that I would pass on my initial findings.

We will ignore the fact that upgrading from an MSI 580 Twin Frozr ( and a very nice card it was) to a 670 GTX was not the most sensible/sane thing to do at 1080 on a single monitor. Especially as even a 680 at best would only give me around +30% improvement. But basically I just fancied a change and no pockets in a shroud, as I'm always fond of saying.

Decided on the 670 rather than the 680 for the obvious reason that it's around £100 cheaper. Looked at the over-clocked 670's to get as near to the 680 as possible out of the box, while saving some money. Top tier cards just loose far to much money (don't I know that one ;) ).

It basically came down to either the Gigabyte Windforce, the ASUS TOP, or the MSI PE. Having owned a 460 HAWK and a 580 Twin Frozr, I quite like the cooling on these and build quality. Would have probably gone for the ASUS TOP, but for all the reported problems and the fact that it looks like it might now have been "pulled from the shelves". Decided (maybe unfairly) against the Gigabyte card as my original 580 was a windforce and it would not run stable at stock vaults and suffered slightly from coil whine. Not looking for a flame war over what card is best, these are just my personal thoughts.

Couple of benchmark results:

1) Heaven 3.0 (settings as per Heaven thread on OCuk) 69.3 FPS, Score 1,746
2) 3DMark11 P8,472
3) 3DVantage Basic settings 38,331 (PhysX on).

Only game played so far to any extent, Alan Wake and that runs solid 60 FPS at highest settings. And it appears quite a demanding game for DX9.

So far my test / experience is that it is around +30% faster than the 580 GTX that I previously had (IE. around what I expected).

Pros:
- Custom PCB with improved PWM.
- Cooled memory and power module.
- Military class components.
- 3 year warranty.
- 22C idle (bit nippy up here in Scotland at the moment).
- Max temp of 57C after one hour of Heaven looping.
- Fan noise. What noise. Except on start up when the fan goes into reverse at 100% for 20 seconds (dust removal), it's totally quiet (well to me it is).
Certainly quieter than my MSI 580 Twin Frozr under load, not like that was a noisy card either. Aluminium PC case sat on the desk about 2 foot away.
- No coil whine.
- Boosts to 1162Mhz solid under load.
- Latest version of Afterburner unlocks three way voltage control. Though not played with this yet. If I have a go, I'll post an update.
- Out of the box as fast as a stock 680 GTX.
- Also looks good and feels well made.

Cons:
- To be totally honest, at the moment I can't think of anything.

Question... The best 670 out there? No not really, but definitely one of the best. Like most things in life, it's a personal choice.

Will you be overclocking this card fella?

If so can you fill us in on how to go about it? I have the same card..

Cheers

At some point I shall be having a go at overclocking. Initially I like to use a card at stock for a couple of weeks to make sure it's 100% stable.

From what I understand... To overclock this card, assuming you are using the latest version of Afterburner (IE. 2.2.3)

1) Increase the Power Limit to max.
2) Then increase the core clock bit at a time (stress testing in between each increment) until you reach the max stable Core clock at the stock voltage.
3) If you want to go further. Then increase the Core voltage a small amount and loop back to point 2) above.
At some point you will reach the limit that the card can make.

Try to keep temps below 70C, as I believe Kepler chips start to throttle above this.

As to the fan speed. Three options really.
1) Leave on auto.
2) Design a custom fan profile.
3) Set to 100%. Though I think you will find this much to loud for day-to-day use.

I'll post back at some point when I have a go.

Good luck if you decide to have a go before this.

PS. Here is a decent general guide to overclocking these sorts of cards.

Seems as though I am have a locked Bios.

Never flashed a Graphics Card before so my best bet is to keep it at stock with minimal overclocking.

What do you think mate?
 
looking at your afterburner on my pc (was on phone earlier), i can see that it doesn't look like you've enable voltage control in the settings? There should be a down arrow next to the core voltage offset slider that will show the sliders for aux voltage offset and mem voltage offset
 
Both about average for 680 lightnings tbh, I've seen people raving about benching ~1400mhz in heaven 3.0 (which i'd imagine is above average) but i can only do max of ~1377 on one and ~1350 on the other.
I've finished my benching for now until EK finish the waterblocks for them.

For example, I heard linus say the lightning he tested would go to 1460 (i think) core, but the memory didn't oc much. I'm pretty sure my 1377 with +630 mem would outperform that.

I do however know there is a method of increasing the afterburner voltage offset to an unlimited amount. So for example If I had the cooling (ln2) I could plow 1.8v or something through the core for a bench.

I have seen people saying then can get in excess of +700 mem on the PE, but anything over 630 for me halves my frames.

1.8v is sick!

+100 mv showing up in GPUZ as 1.175v, is that the max a 670 can do?

P.S Do you have any Pics of your setup on this forum? I have the same case and Interested in custom cooling.
 
I'd never bench something like that though. Anything 'above' water is not only beyond me but also not my idea of fun lol. 1.8v would break my cards under water really quickly, on air you'd have to be insane or dumb to put those kinda volts through lol.

The +100mv should net you around 1.275

Can't remember, here's one. Naff lighting but I'm not finished my build yet anyway

Did you unlock voltage monitoring? GPU-z and other programs will always read 1.175 so only go by what AB says. If it's still maxing at 1.175 then I guess it's true that nvidia have forced msi to lock the voltage. I had read that they released a new bios for the lightning at nvidia's 'request' but that it failed to prevent overvolting on the card.

You can find original the original PE bios around the net if you want to flash it.
 
I think I'll leave it for now, will take a proper look tonight.
Never flashed a video card before, so I am a bit skeptical of it all.

Would like to see how far i can push this baby though. =)

Your setup looks very tidy, I am glad you kept the 180mm fans.
Looks like you kept the fan filters on too?

Soz @mikeo for taking thread away ;)
 
Yes the rad is external under the desk. I physically cannot fit a rad in this case without removing the fan filters and sliding assembly anyway, the cards are a smidge longer than 690s iirc.

I have thought about getting a custom-made demciflex filter for underneath and removing the mechanism/filters/hdd cage and putting in a 180x3 rad.. we'll see.
 
Custom-made demciflex filter for underneath sounds beastie, with magnetic strips or something?

Let me know how you play it out fella, very interested.

I have an H80 in my rig at the minute but looking at custom cooling, though probs be a waste of money as I won't find a block for my 670 :p

As far as I am aware... no software tool can read the voltage off these cards. You'll need a DMM (Digital Multi Meter) to do this.
