I am currently interested in overclocking my IGP (HD 4000), and have read that overclocking the RAM will help. I already have 16gb of RAM at 1600, is pushing it to 1866 or higher really going to help.

Does increasing frequency(1600->1866) and increasing latency(CL9->CL10/11) essentially have a 0 effect?

In this case little to none, might pick up 1 FPS or 2 depending on game and if it's mamory centric, but base performance level 1600/9 is about equal overall to 1866/10 - you do pick up additional bandwidth at 1866, but here it would be negligible....if you you manage to get it up to 1866 and keep CL at 9 that would be a more worthwhile project, but would entail balancing voltage and getting into advance timings

Suppose i were up for such a an endeavor... know of any decent guides. I would say i probably know enough about RAM to be dangerous but not enough be certain im being relatively safe.

You'll maybe get a 3-5% boost to a ridiculously poor IGP and that comes with plenty of risk of system crashes, an AMD chip is what you should have gone for when running IGP. Get a graphics card. This site has regular updates on the best graphics cards for the money.

I realize that IGP is a poor solution but you would be hard pressed to get me to support AMD's CPU offerings. I also recognize that a gfx card is a much better solution however its not really for any reason other than i want to try. I think its important to recognize that my max output resolution will be 720p, and before you go saying to spend the money on a monitor, i cant and wont. I have a 155" projector in my house that is used as the screen thus any screen replacement to a higher resolution will easily cost more than the entire computer.

On the DRAM, can definitely try, and I will try and help as time permits, if you do want to, before getting started will want to know CPU (and current OC if any, actual Model of DRAM, and mobo (will want latest BIOS)...also all system voltages and DRAM timings both the base i.e. the 9-9-9-24 or whatever and all the advanced like tRC, tRFC, tRD etc

LOL been seeing you all over the boards today. I actually recognized your tag from over there while doing a search for this. But since it isnt only memory based i thought i would start my search here. Like I said Im game to give it a go.

AMD are weak right now with CPU's but their IGP's are lightyears ahead of what intel can offer. The only option you have is to get a graphics card. You don't even need a good one. Anything over... I had a look at the list and it's depressing here is a list of graphics processing devices and you could probably find one of them that is better in the recycling centre.

Ah yes this is true but my desire to tinker is greater than my desire to just purchase something that works. Im sure at some point when im done tinkering with the IGP, I will end up with a discreet graphics card but for me its not about just getting it to work, its more about learning the how and why. Hence all the painstaking hours researching every little thing to get the best possible value with the most amount of useable performance.

I'll be around, actually just planned to hop over here to help a couple of folks from the GSkill forums, they wanted to know if I could help with some Corsair DRAM.....and I didn't really think it appropriate to be doing that at GSkill's site, apparently we got their GSkill rigs nice and smooth and they were having problems with some expensive Corsair sets, I originally suggested (via PM over there that it was a tRFC problem - they were mixing some high freq sets) so they emailed Corsair, and were told the sets wouldn't work, they finally got a phone number and asked a tech...he didn't even know what tRFC was, turned out they had a mobo that limited tRFC to 255 (ideally they needed 278), but we got them going with changing a few of the others to compensate...while dealing with that sort of got hooked here...there's a lot more people out there than I thought, that know extremely little about DRAM

OK, keep your current settings, so you have fallback, and might run MaxxMem or go to command line as Administrator and run WINSAT MEM and jot down what it comes with..... Then lets start with setting DRAM to 1866 base timings at 10-10-10-24 and raise DRAM voltage to 1.6 initially (yes, it's safe) and set CPU multiplier at 38, we are just looking to see what happens at an easy 1866

ok so i went through and tried to do that. It started to through the Bios splash screen, tried to load windows normally, then flipped to what looked like it was going to be safe mode, and then before it could launch BSOD.

The following article SemiAccurate talks about overclocking the Intel HD 4000.

In summary using Intel's Extreme Tuning Utility the writer was able to overclock the Intel HD 4000 by 39%, however performance increased by a little over 10%. Increasing the HD 4000's TDP from 35w to between 45w and 52w TDP, the increased performance to almost 16%.

Thx I have seen the article. It doesnt quite cover how he went about it in detail but more about the results he achieved in his endeavor. Id like to know the steps that he took in order to find a stable overclock as well as what settings were played with. To make it more difficult I believe he was using a gigabyte board and im on asus, although in principal the bios' have the same effect they are not the same in form.

Just to toss in a thought on the BIOSs between Asus and Gigabyte - can well be worlds of differences in how the companies approach things, I think Gigabyte takes a more proacttive approach and tries to get things done faster than Asus, Asus takes a more reactive approach - as people complain and want more then Asus acts, in it's own good time, which in part has been involved in their decline of sale where GBs market shares increases

just tried messing with a few settings that might have been interfering with the ram being able to get all the voltage we would like to apply to it, and I got it to boot with an error, that seems to run the os but I have a black screen with nothing on it. CRTL+ALT+Del pulls up task manager and allows me to function a bit. any ideas?
