Z77 - 800D Build Log

[Drdeath]

Thanks!

Hey Sam, I am sad to report that my 8120 chip isn't a good OC at all. Not only that but I updated my Bios on my MB and the OC is even worst.
I have not been able to get anything stable at 4.4ghz. Even running volts as high as 1.56v and as low as 1.2v.

I even upgraded the cooling to a Triple Rad and better fans and still no luck. Although heat isn't the issue I have a feeling its the Mobo and not getting a good binned chip to begin with.
I am looking at trying to pick up a better mobo at this time, But I really don't want to have to spend $200+ on another board. I am looking at the Asus Sabertooth 990fx board right now..
From the research I have read the Saberooth is really good at OC the FX chips, I thought about the board you have but then again not sure which route I would take just yet.

Another problem is that since I got my Giga board when first released I got the Rev 1 board which doesn't have the load line calibration which is making it hard to me to acheive better OC's without the board throtling down the chip or BSOD.
Which is another reason why I haven't posted much updates. Until I have time to figure it all out or get a better board I won't post much yet. Or unless I figure it out with the current board. As of right now tho, I am not really happy with the performance. With the rev 1 board, everywhere I looks everyone has had problems. The best thing to do is replace it with a better board.

I can get 4.0ghz stable, but anything above that will have problems.
at 4.0ghz my temps right now are at about 48c at full load with volts at 1.41v

However performance wise at the same clocks my 1090t performs better and much more efficient..

Kenny, you need over 1.5 volts for any major overclock. Disable cool n quiet.

Hey Jim, I tried that... all the power saving features are disabled... I actually followed one of your older post you have here on clock settings using the same board and no luck.
Once I put load on it, it dropped back down. Due to the rev of my board without the load line calibration I am having a tough time getting higher OC. I've been playing around with it and I am going to keep trying. Like I mentioned before last resort is a diff board..

[vinman]

is your ram at stock settings?

if not set your ram at stock settings and try that

I can get 4.4GHz stable 3 hours prime with only 1.4 volts, and 4.6GHz stable 3 hours prime with only 1.425 volts. Can't push any higher right now with my present cooling. I tried for 4.8GHz at 1.45 volts but temps went over 65 C on the cores so I shut down prime. I know not all chips are the same but this is what mine will do in my Crosshair V board. If I had custom water, I think I could get over 5GHz with my 8120. I think I have a binned chip or something. Maybe I'll get lucky and win the XSPC kit in the week 11 giveaway and then we'll see what I can really do with my FX chip.

There is 8GB installed during the bench. Ram also all at stock settings.
I am going to try to being it down to 4GB and see what I can do..

Worth a try, but I think it's the board like you've said. I'm getting the oc's above with 16GB of G.Skill 1600MHz at 9-9-9-24-33 2T.

[Solara2xb]

im going to give it a shot and see what it does. I have a feelings its going to be the same problem. But I am going to put it to its test...

[Drdeath]

Its not the board guys. All top name boards pull overclocks within 100MHz of each other. The chip needs more votage. There is a point that a little more voltage does not get ya the extra multiplier where it may need .3 or .4 volts more.

[Solara2xb]

Ill try to pull more volts, but I don't want to fry my chip. I already had it set to 1.55 at 4.6ghz and once I pull a load it drops it back down. Again Vdroop...

[SamCR3]

I know each chip is different, but I don't understand the huge discrepancies between Kenny's 8120 and mine. Why can I pull a good oc with low voltage and he can't? Like I said, I run 4.4GHz 24/7 at 1.4 volts and can hit 4.6GHz at just 1.425. Only thing I can think of to explain this large discrepancy is either a crappy chip or bunk board. Am I wrong?

[realneil]

Some chips do better than other, like chips. It's like a lottery.
What board you have can make a difference too. My Sapphire board is rock solid until you try to OC it. Then it Sucks.

Some Updates on my 800D (02.15.13) I had been running my GTX670 on here for a while, but I had it on air since I didn't have time to change the loop.
Over the last week or so I finally had the time to change it over to water with the XSPC Block. I also added a GTX650 for a dedicated Physics card along with it running my 2x 19" Dell Monitors, this way I have the GTX 670 Dedicated to my 24" Dell.

Runs much smoother now...

Thats all for now

[SamCR3]

Can you explain a dedicated Physics card, what the advantages are and how difficult is it to set up. I know nothing about it and am curious.

[realneil]

That's killer.
It should work great.

Sam, the Phys-X is a NVIDIA option.
Having a separate card for Phys-X processing leaves the primary card with much less load on it, improving performance.

If there is an AMD card in the system, Phys-X will not work.

What Neil has already said, its for nVidia cards, Having a separate card for physX calculation will help the primary card to process the data it needs without robbing performance from it.
While most of today's modern card can handle the physX and processing on a single card. Having a dedicated card IMO is much better leaving the raw power for the primary GPU to perform to its full potential, basically not sharing it with anything else.

The other reason I did this was to also run my 2x19" Dell Monitors off it, this way I am not putting more load on my GTX670 and leaving all the power on its own. I am seeing better performance this way.. Since I am not running my 2x19" in surround mode, it didn't matter. however, like my TH10 build where I run all 3 of my 24" Asus monitors in surround mode to get 5760x1080 resolution, I can't do that set-up. However I am looking to add a GTX650 so that set-up so I can run physX of it. That is if I can find another good deal on a GTX650.

I got the EVGA one for a steal on eBay.
