***The Official Core i3 Overclocking Thread***
- Thread starter easyrider
- Start date
building a H55M-UD2H, i3 530, 5770xfire system soonLooking forward to overclocking it. Can I get 4GHz on air? Might look at 3.8GHz with AC Freezer 7 pro v2
I hope so!, im aiming for 3.6-3.8 with stock cooler, and below 75c stress

well i give up on 4.4ghz, at least for stable 8 hour tests. i can get it to work fairly well, but after an hour or so of gaming it still crashes. it must be overheating, and im just not going to go crazy on the cooling right now just to have an extra 400mhz. i dont think its just the cpu getting above 80c, i think the motherboard has trouble after long duration as there isnt any little cooling fins on any of the regulators or anything...
at 4ghz, ~733mhz ram, 182x22 the system is rock solid stable and lightning quick- and cpu voltage 1.3v whereas 4.4ghz needs 1.42v+. it just doesnt make much sense to run above 4ghz unless you have crazy good air or a water setup.

Almost the same as what I have concluded, 4GHz is deffo the sweet spot for these CPU's.
I can hit 4GHz with 1.31V with ease.
But to get 4.2 I have to go to 1.375V, and 4.4 needs a similar jump in vcore again.
Those review CPU's must have been cherry picked samples as you just aren't going to get 4.5-4.8 on reasonable voltages without some immense cooling and a whole heap of luck.
Still don't let that put you off, 4GHz is still a lovely OC, and the chip is lightning quick!
I have the i3 530, GA-H55M-UD2H, Patriot Sector5 PC3-12800, TX3 cooler, HD4350 and running W7.
It is at 4GHz now but I have found some problems, if anyone can help me:
CPUz shows Link width at x1 and there are no memory timings; at a lower OC of 3.5GHZ link width was x16 and there were mem timings.
When I shutdown with any settings the PC doesn't shut off the fans, cpu fan or PSU fan - very annoying!

exactly my results too.
i am loving this speed though. grand theft auto 4 plays at 1080p, textures medium but everything else cranked, even with vsync and its a silky smooth 60fps. it just absolutely kills my old e5200 at 3.7ghz on the same 8800gts video card. that old setup couldnt even run 720p vsyncd....
ive noticed i cant do the settings you have hex- this asrock board just doesnt like 200fsb, at least in my configuration of parts.
however, my memory does run a ~910mhz even with 182x22 and a 4000mhz qpi so things are seemingly settling into this setup. i didnt expect this to be this much of an upgrade from the e5200, but it sure wasnt a waste of money

the fan that came with my ac freezer pro v2 was dead, so at the moment I have passive cooling goingwith the heatsink alone and only a front bottom hdd bay in fan. underclocked to 2.4GHz and undervolted to 0.9V does the job really nicely, temps wont go above 60 on load and the silent 5770 vaperx makes it oh so sweet for a £450 build. When we rma the heatsink I shall invest in a 4GHz overclock which I hear is possible with the intel heatsink if its a good or cherry picked cpu.
Managed to get it up to 4GHz QPI last night stable as well, but didn't improve anything so knocked it back down to 3.2, no point stressing it for no gain
I'm very happy with the settings i've got now. Haven't had to adjust any of the other system voltages, i've got them all manually set to defaults, only had to up the vCore to 1.30625 (1.312 in windows), and give my mem 1.65V (stock).
Sounds like your board needs a bios update to get you up to the 200FSB, there are deffo a few bits this gigabyte board could do with tweaking, but that's what you have to put up with when you buy first revision stuff I guess.
Resins, could you do me a favour. Are you running a dedicated GPU? if so can you run resmon (just type it in Run), go to the memory tab, and see if you have a chunk of memory greyed out as 'Hardware Reserved'.
My friend and I both have H55M-UD2H's and they both have 133MB reserved (lowering our available mem down to 3.87GB), and I just want to know if it is all H55 boards that are doing it, or just these gigabyte boards.
well my board wont let me adjust the qpi... the option is there, but its always greyed out to AUTO
ill check my memory, but im fairly certain it is using some. reason being is i had to actually enable the onboard gpu just so i can overvolt it... thats the only way i can play games smoothly. the system will actually run prime95 stable, but any 3d app just crashes unless i turn on the onchip gpu and bump up the voltage.

OcUK solved the shutdown problem with the mobo; it required a BIOS update and now is on F5m.
Have it running @4GHz 200x20 and am lowering the Vcore; so far at 1.264v - 1.25v in BIOS. Screenie below
Should I expect quite such a difference in the temps. of the two cores of 17C?
NB I have a HD4350 installed and available mem is 3.87GB

You do realise you are only stressing one core by using Orthos...
You need to use the latest Prime95 to stress all 4 threads (and thus both cores).
Good to know about the mem, seems all the H55 boards are stealing a chunk of memory.
The F5 bios was totally unstable for me, glad if fixed your issue however
