Seems a good start Ivan. 4.1G with <1.4V is not too shabby is it? What's default Vid?
Yes, not that bad, but not better than the other one I have. I think most of the new 1090T can do the same with water cooling. Default VID is 1.3V, if CoreTemp is a good way to see it. It idles at ~1.28V (multimeter) with "auto" set in bios.
The first test I did was to put it in the socket and see if it's stable with the settings I use for the other one. Well, it locked up. 4.3GHz is doable with around 1.5V real voltage.
It doesn't mean that It will remain the same when an overclocked CPU-NB is added to it.
I've already read tons of reviews on the Crosshair IV, so I was about to pass this by, but I thought I would take a look at their overclock:
http://hardocp.com/article/2010/11/1...board_review/7
I was always curious how some were able to exceed 300fsb, beyond just luck. Well, I found my answer: "CPU VDDA voltage", or, on other boards, CPU PLL voltage. I generally leave PLL voltages alone, but it looks like this particular setting helps with high FSB overclocks (also see their MSI results: http://hardocp.com/article/2010/07/2...board_review/1, again, higher CPU PLL voltage)
Even with my posted stable settings, I found myself sometimes being booted to desktop after long gaming sessions... lowering the FSB one notch sorted that out. After bumping the CPU PLL up one notch to 2.54, it looks like I can go back to my initial "untested" settings of 289fsb... I just past a 50-run on IntelBurnTest this afternoon. I'll do a 400-run tonight to confirm and update this post.
***Update***
Bah. 289 didn't pass overnight testing. Even 288. Back to 287. Looks like my RAM is at it's limit. Dropping timings and clockspeed down and upping CPU PLL to 2.7 for a max-fsb-test got me to almost 300, but it would not perform as well as my highly optimized timings. So, I'll stick with what I got.
They didnt seem to tweak the CPU-NB any with 1.45 on the CPu-NB I figured they would make a little more head way on the CPU-NB anyways I will give the VDDA voltage a go and see if it stabalizes things for me.Quote:

Quick question, should I lower my ht link speed on that overclock? I notice a lot of people have it around 2100, I have mine at 2700.
ht link is for cpu to graphics, which is quite fine even at 2000, so i would say yes, but after some testing.
some people i believe notice a loss in perf if NB and HT are not identical. not sure how true that is.
but lower the HT might let you get some extra clocks out of it. i would just drop it 1 multi so your around 2300-2500ish
darn double post
match HT and NB. in everest you'll notice cache and memory latencies improve quite dramatically.
Alright thanks, I'll play around with it then to see how it goes.
Can you give me some proof?I have same board as you,only i got 955BE c3.I have a pretty good CPU-Nb,doing 2800 1600 6-6-6 full stable at 1,25.But there is no difference if i match HTT with CPU-NB or not,it gives me zero performance,no difference whatsoever.Maybe it has something to do with Thuban?If you can give us some Everest screens would be great :DQuote:

I have read it alot on here especially with the 890amd mobo's, I tried it myself and it turns out to be true, When overclocking with FSB on a 1055t its best to keep NB and HT sync on 890amd boards, but if are you going to you'd need to increase PLL voltage and NB/HT voltage.

Nice chip there.
I have a question for the CH IV guys. Just started playing with this board and it seems to over volt quite a bit. For eg. for 4.2 Ghz, am running prime and it moves from the 1.45v i set in bios to 1.50V....now thats a huge movement in voltages. This is basically becasue of CPU load calibaration being on. When I put it off, it undervolts and basically black/blue screens during testing...Damn I cant get the volatages to be stable. On my earlier board, the MSI 790FX GD70, it would undervolt a bit, but would generally stay in the same range. In this board, it either undervolts or overvolts a lot. Now the issue for me is that even with a water cooled system, I am touching 60 degrees on the cpu when running it at 4.2 Ghz 1.5V (1.45V in bios). Can someone help me here.
Are you wanting to replace your previous entry with this?Quote:

just have to get used to chIV overvolting so much :shrug: what is your water set up? i was able to run 1.56v @ load with temps around 55-56c but i have 3x120 worth of very high fpi rads with some 100+cfm fans on them to keep those temps. x6 gets much hotter than x4 with same volts, but is usually able to get higher freq with same voltsQuote:
