Hey...We almost have identical systems

Hi5! LOL :lol:

[SkilledRebuilds]

How far (on average) has Hynix been pushed on these G1's.???

 

Thinking of giving the Mem OC another crack...

More curious to what it can do. Or what the 'average' people are getting for these specific Hynix G1 cards.

Should I aim more airflow on the backplate of the card to help the mem-chips in any way? Is this a thing for these?

 

Core +145 & Memory +345

/Dat moment...so far so stable @ 1550/1925 in FC4 for 30mins (8xMSAA 900p Windowed) (Have more games ready available to test)

(Mem-Clock @ 4000Mhz Effective or 2000Mhz) artifacted, hardly but I saw it after 20mins, had to back it off to 1925, slowly moving up again to find max.

Probably only thing that's going to help for memory OC is little heatsinks on memory IC's.

Airflow kinda helps.

Samsung memory (at least mine) is unstable at high temps. I'm actually looking to replace my 2 intake fans for some Redux NF P14's to increase airflow.

[SkilledRebuilds]

I have a fan at 45* angled up under it feeding it nice cold front intake fan air.

Will move it to the hdd cage to provide backend airflow and see if it helps.

[Vellinious]

Bored, so I beat up on my GPUs again.  I'm thinking I've pretty much reached the limits of what they're capable of.....

When I had my G1 Gaming my mem was capable of 2150 with some decent airflow, I think I had a REALLY good memory batch.

[Vellinious]

I was wrong...Elpida memory CAN overclock quite a bit higher.  Just gotta keep it REALLY COOL.  Heaven run at 1586 / 4205

Hello, can I flash my asus strix gtx 970 with bios provided in first post?
As I understand, if I will flash my card with custom bios, GPU tweak utility will allow me to crank voltage more than now (1213 max atm)?

Strix is hardlocked, you can flash bios, but nothing will change.

Nope.  The STRIX 970 is locked at the VRM at 1.212v.

Hi guys. Anyone with a EVGA 970 SC (with the ACX 2.0 cooler) that has any experience with overvolting? I'm currently running a stable overclock of +150mhz on the core and +100 on the memory, for a total of 1315mhz base clock and 1874 base memory clock. The card is boosting to a little over 1530mhz, which I consider pretty good. I have not touched the voltage though. Overclocking through PrecisionX, and no changes to the fan curve. Stock BIOS.

 

How far can I push the voltage before the card is in any danger?

Maxwell can run up to 1.3v before it'll start to degrade.  You won't get but 1.256v out of the stock bios though....so, have at it.  You WILL, however, hit your power limit and start throttling due to perf cap reason "PWR".  If you haven't already.

Yeah, I just found out that it doesn't matter as long as I'm on the stock bios. Oh well.

[Vellinious]

Yeah, the stock bios on pretty much all Maxwell cards is very restrictive.....doesn't allow for much room.

The card is still running stable (so far, at least, having tested it in Unigine Valley and The Witcher 3 on max settings) with a pretty good overclock. Pushed the memory to +350mhz now, not seeing any artifacts or crashes, and with a custom fan curve I manage to max out at 74 degrees. So far I'm very happy.

[GiedriusQ]

Nope.  The STRIX 970 is locked at the VRM at 1.212v.

But I wondering how Luke was able to increase VRM to 1.265v in this video

according to this spreadsheet https://docs.google.com/spreadsheet/ccc?key=0AmLKAgEko3SAdHFtby1jNTFvaTF2UHhaMzdMQ0FNM2c&usp=sharing#gid=0? :huh:

At what point in the video does it show the card at 1.256v?  Or that someone says the card is running at 1.256v?  All I heard was "bump the voltage, bump the core" etc.  Which....he's wrong about.  = )

I left a comment on the video....we'll see what he says.  lol

Just because he increased the setting doesn`t mean that the card would use it. If the voltage controller physically is not capable of delivering more than 1.212v, then only physical changes can make it use more.

[Vellinious]

Well, yeah.  Unless they ran a custom bios on the STRIX 970, they weren't going above 1.212v no matter what he did to the card to get around the limits at the VRM.

VRM and im fairly certain the voltage controller also runs at a lower pwm freq hindering clocks too.

Could be...I've never messed with one myself.  I've tried to help a few guys mod the bios files, but....the most we could ever do for them was to raise their power limits.  

[Beneh]

Hello all, I've just finished my first custom loop and I'm running 2xMSI GTX 970 Gaming 4G's. They're both using Hynix memory, with ASIC scores of 71.4 & 72.1. What should I be expecting from these cards? or, what's their potential like? After a number of hours benchmarking today I've managed to get them stable at 1571mhz core & 7552mhz mem. That's with the voltage slider @ +87 in Afterburner. Afterburner reports instances of the cards hitting 1571mhz core, but GPU-Z says my boost is 1483mhz. Little confused there. First time overclocker, been building PC's for a very long time, yet never ventured into OC/watercooling territory. Any pointers much appreciated.

GOT IT!!  FInally!!  28k graphics score!!

can you make a stock voltage 0 % fan as minimum please for g1 970
