Other than that, not sure. The latest beta BIOS release on my (and others) Gigabyte boards allowed use of 2400 XMP profile without adjusting anything else.

The timings were adjusted by the XMP profile.

The timings listed for my gskill Ares memory to operate at 2400 are:

11 13 13 31 1.65v

Aside from using the XMP profile, anybody have suggestions on what to set to get it to work given these timings/voltage?

I updated my BIOS as suggested and tried using XMP but windows crashes shortly after getting to the desktop. I tried upping the NB voltage to +.102 but it didn't help. What other settings do I need to change to run at 2400 (using XMP or not)

I would check the heat of the Northbridge. On my gigabyte board it was labeled as System temp and was always mid 50s figured it was just another bug. Come to find out upon touching it the NB was super hot. So I took off the heatsink to find it was barely if not at all making any contact.

Mind you I could barely get to boot at 2133 with loose timings.

Now after taking off the sorry excuse for a thermal pad and putting some TIM there and a fan blowing, turned heat almost off in my house my NB temps are mid 20s and I am running 2400 speed ram at Cas 9 11 11 31. I have a rma board coming in though as I think the NB got damaged from no real heat dissipation.

Also XMP doesn't seem to work well for most and many people are just manually entering in the values.

You could try bumping the dram voltage to 1.7-1.75 to see if that stabilizes your RAM at its rated speed. Shouldn't really be necessary but most kits nowadays are geared towards Intel setups and don't always play nice with AMD stuff.

Hrmm. MSI Board just broke 6ghz. http://valid.canardpc.com/wwcaeu

For a sec, I was gonna say "that voltage can't be right, there's no way!" but then I saw it was done with just one core enabled.

Still, pretty impressive. Is the G45 available anywhere yet?

Using latest version of Easytune as I write this the system and cpu temps are both reporting 24, with some fluxuation for CPU. Not sure if in this case 'system' is the NB but I've looked at several temp programs (coretemp, HW monitor, etc) and I haven't seen any temp issues (as far as I understand anyway) and this is with my ram at 2133mhz.

Run prime blend test or custom and a good amount of ram and monitor system temp

So I literally just read through all posts again...haha... got some beneficial information, but still feel like I haven't gathered a consistent enough agreement on what does work at what settings... everything seems to focus on what doesn't work. I know it's part of the process, but it's a bit exhausting to need to parse through so much when the thread is, after all, titled "Overclock Guide," not "Overclock Problems." That's the end of my mini-rant, because I do see the merit in the problem-solving process, obviously... I'm sure someone will reference a few posts out of the 350+ here, but that's unreasonable to declare as a universal agreement/guide.

Has anyone found any success at the following speeds, and if so, what voltage and/or settings were used/disabled?

CPU: 4.3 GHz
RAM: 2400 MHz
iGPU: 920+ MHz

CPU Vcore? NB Core? Take the easy route with Memory and use XMP, or manually configure based on CPU-Z and/or Manufacturer specifications?

My motherboard is a Gigabyte F2A88XM-D3H running BIOS v. F6b. I've seen this mobo mentioned a few times along with other Gigabyte mobos of the similar type, so I know there has to be some certain "safe" parameters at least to provide a baseline set of ranges or specific figures for people who aren't familiar with overclocking APUs in general, not just this particular one, or who don't need to get the absolute highest OC numbers.

4.5Ghz @ 1.45v and Extreme LLC. 960Mhz on the iGPU with Extreme NB LLC. XMP at 2400.
I think there's more to squeeze but at the voltages required (and better cooling) not worth the extra power use imo.
Little disappointed in the iGPU 960Mhz cap and CPU 3Ghz throttle but maybe that will be corrected with a future BIOS release. Would also be nice to see higher memory presets.

Many thanks, sorry to have come off a bit ungrateful and needy! Literally just plugged that all in as a hail mary blind instruction from you and so far, booted into Windows 7 no problem. Running some stability tests soon for myself just to account for any role minor hardware deviations have... then gonna run a few benchmarks tonight to try to compare it to some other rigs I have/had... I should probably get to making my profile sometime soon... rolleyes.gif
