Calling all vintage knowledge holders!

The boards not so good though. Only a 4 pin cpu power plug and no vrm cooling at all. Might be worth getting some Enzotech mosfet heatsinks to stick on the vrm chips. Did the guy you bought it off have it overclocked? If he did he may have left the settings on it. If he didn't overclocking is easy anyway. Set bclk to 200 and multiplier to 38x, add some vcore (around 1.3v) and you have 3.8Ghz. Add a bit more vcore and set the multiplier to 40x and you got 4Ghz. You may have to play with IMC and PCH voltage but that's about it.

I have just ordered some of these Enzotech heatsinks, so all being well I'll be swapping everything over this weekend. Thanks again for the advice :cool:

Other than that the motherboard / cpu / cooler / and RAM is all made up ready to go:

Oh I've also purchased a GTX 770 with all the nvidia price drops but this will be going in the new rig I'll be putting together in the new year :D :D
 
No. They go on the little flat square chips below them. See those two lines of chips to the bottom and right of the socket, like a reverse L shape, that's where they need to go. You have them on the chokes which don't need cooling.

Ok I now have some slightly bent heat sinks from moving them but does this look to be correct ?

Do I need to cover anymore? I have two left and there are a couple of small chips on the board

Thanks
 
That should be ok for now as long as you don't push it too much. It's a pity you couldn't get the smaller Mos-C1 heatsinks as they are much smaller and designed for individual vrm chips. You would have got the two you can't get heatsinks on then. Still one heatsink per pair of chips is better than none at all. You should be good to go now.
 
All installed:

Didn't boot first time, I assume because of previous bios settings and different hardware, but booted fine on the default bios

Overclocking session tomorrow night :cool:
 
Tell me about it they're being ripped out tomorrow night I left them in just in case I needed to reinstall windows and I knew that method work - hey at least they're almost vintage :D :D

This is also weird - after the first boot windows 10 "installed devices" and worked perfectly with the new hardware! Not sure if this is intentional or not but very impressed with windows 10 if it can handle large hardware changes like that

I will probably do a fresh install one night this week though

Hey Pasty is the above advice correct?

I've been reading various guides and they all state that cpu frequency is determined by bclk x the cpu multi, so 200 x 20 would give a 4ghz speed ?

Thanks
 
It's same as the fsb + cpu multiplier overclocking on 775. On second thoughts, maybe 3.6Ghz (36x200) would be a better starting point. Don't forget to check the ram speed as well. Raising bclk affects ram the same way as raising the fsb. You still have to keep the ram in spec. What ram did you end up with? The reason i said run the bclk at 200 is that it is easy to keep 1600mhz ram at it's rated speed with it set to that.

But 36 x 200 = 7200 ?

Surely it would need to be 200 x 18 for a 3.6ghz clock?

I ended up with g skill ripjaws - pc3-12800 - so yeah 1600mhz if I understand ram correctly

Sorry for the 101 questions I just want to make sure I fully understand it before diving in :)
 
AAAArrrrrgggghhhhh. Forget what I said. I have had a really stressful day. I was thinking of my current cpu. I meant 3.6Ghz (18x200). My old 760 did that on stock volts so would be a good place to start then you can work up to 4Ghz from there. A bclk of 200 means that by adjusting the memory multiplier just the once you can keep the ram at 1600mhz and overclock just by using the cpu multiplier and voltage.
 
Nice one thanks for confirming, had me worried for a moment

You're just checking that I'm reading your posts really aren't you ;-)

Going to give this a go tonight
 
I've got it sitting @ 3.8ghz currently - temps are hovering around the low 60s under full load.

Seems fairly stable at the moment but I need to do more stress testing, I had an error at 200 x 18, but it seems happy at 190 x 20 so I think it was the memory causing the problem.

Will perform more tweaking and stress testing this week, I think I'll be able to see 4ghz with the right config.
 
If you had the memory at 1600mhz it won't be that. It's more likley that it needs a tad more voltage for the chipset. Different manufacturers have different names for voltages but here are my settings that I needed for 4Ghz and 4.2Ghz on my 760.

4Ghz

20x200
Vcore 1.2875v
CPU PLL 1.8625v
IMC 1.16250v
PCH 1.0875v

4.2Ghz

21x200
Vcore 1.375v
CPU PLL 1.900v
IMC 1.13125v
PCH 1.15v

All other voltages were set to minimum or auto and it was rock solid at these clocks. Note the big vcore increase for just 200mhz extra though. This is the reason I ran it at 4Ghz for day to day usage.
 
Ahh right, the chipset voltage was one thing I left alone so I'll have a play with that later

I put the vcore to 1.35v with a plan to work down from there, but 60c didn't seem bad under load for that

My memory is also set at the default 1.5v - will this be ok as is?

Thanks for the info
 
After reading a guide again, I think you're right as increasing the bclk does directly impact the chipset and subsequently it requires more voltage.

The guide recommended a start point of 1.2v for the chipset - which of your above settings does this relate to?

Also, with the Gigabyte boards, is this QPI/VTT ?
