2500k. Wont boot anything but Stock and 4.7ghz

[grkM3]

I truly don't understand why anyone would even bother oc'ing their RAM, it makes little to no difference in real world applications. Especially if it involves overvolting the RAM (not smart).

http://www.anandtech.com/show/4503/sandy-bridge-memory-scaling-choosing-the-best-ddr3/6

Why? To thump your chest over a memory benchmark? I'm pretty confused. Oc'ing from DDR3-1600 999-24 to DDR3-2133 results in a .2 fps increase in metro 2033, and no difference in crysis 2. IMHO all that energy and effort would be better served on a better cpu or cpu/gpu overclock.

jee ever heard of overclocking as a hobby,my motherboard was over 300 and what better cpu can I buy for the 1155 platform?

I think ill keep the new board since its one of the only boards to have 2 16x pcie slots.

and running the ram at 2260 saves me about 10-15 min encoding a bluray.

IM at 5.2-5.4ghz so I think my cpu over clock is good bud,try to not waste so much energy worrying about how others play with there hardware.

If I wanted to run at those speeds I wouldnt of paid the 200 dollar premium over a regular board for 24 phase vrms to be able to clock them this fast.

If you are wondering why you cant get over 5.ghz stable with a sandy its because you bought a low end board.

So what's the problem, either stock or 4.7 sound fine?

I agree! I'd go with 4.7 IMO .

 

[grkM3]

any updates?

be carefull on the ram volts also,I just rocked my chip and threw in my old 2500k,my 2600k wont even post now with 4 sticks at 2133 and it was 100000% stable for months until I tried to push it last night and upped the dram to 1.685 and that was enough to strees the memory controller enough to screw it up.

Im so upset since that chip did 5 ghz on air with 4 sticks at 7-9-8-2t at 2240 mhz that gave me over 26000 mb/sec mem bandwith.

Im also changing my board and getting a ud5 or ud7 gigabyte board

100,000% stable? That's even better than ludicrous speed.

Common sense says leave it at 4.7Ghz ,,, and be happy.

I just got the P8-z68-V PRO today. I will update tomorrow.

SO FAR THOUGH, the install and everything has been very smooth.

For the opening poster,

I had a similar problem with my ga-p67x-ud3 board. The PC would lock on windows booting, no blue screen, just a hard freeze. Even with stock it would freeze.

I found that turning off c3/c6 would fix the issue but whats the point of losing key power saving features right?

After like 1 month, I was going to RMA the board. Until somone suggested the RAM. I ran memtest and the ram passed overnight. But I still was suspicious it was the ram.

The problem was solved by increasing all the ram voltages. Not just the ram vcore , but the refs, the termination voltage, the channel voltages. I increased them from 0.75 to 0.815 and all the issues went away even with c3/c6 on.

Yes I am quoting myself! lol

Well to update....ASUS P8Z68-V Pro is like night and day when compared to The Asrock Extreme6.

My Setup:
Intel Core i5-2500K Sandy Bridge 3.3GHz @ 4.5GHZ
ASUS P8Z68-V Pro Intel Motherboard
Hydro Series H80 Liquid Cooler
G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
2 x Zotac Geforce GTX 460 OCed
64GB Kingston SSD (boot / most used apps)
500gb Barracuda 7200rpm Storage drive
ASUS 24X DVD Burner
XFX XXX Edition 650W PSU
ASUS VH238H Black 23" Full HD HDMI LED Backlight LCD Monitor

The only personal annoyance I had with this board:
When I was installing the motherboard, I would like to mention if you going with something aftermarket for a cooler then it wont be impossible but it will be difficult. The chipset heat-sink does get in the way however with a little work it all goes together eventually. The placement of some ports ( 3-Pin Fan, 8-Pin Power Connector) are a bit awkward but nothing to really mark this board down for.

When I first turned the board on I had a very annoying Marvell Sata 6 try and recognize my SSD and my 500GB harddrive. I went into BIOS and turn that off. The BIOS is very user friendly and has a very stable feeling to it.

I installed Windows 7 64 without a hitch. I updated my BIOS right away which was a 2 minute painless process. I then restarted and went into BIOS and changed my CPU multipler to 45X. No voltage changes, No fiddling, No blue screens. I booted up into Windows, and have been running Prime 95 @ a cool 50C load with a idle @ 27C @ 1.325V. As some of you might know from my previous threads or from threads over @ Anandtech, I could only boot into windows with the AsRock Extreme6 at Stock, or at 4.7ghz @ 1.425. This is a big improvement!

Not a perfect board but next time I purchase a motherboard, it will be a ASUS.

+1 ASUS
-1 ASROCK

Glad to hear its working out for you! Just a small tip, put your SSD drive on the marvell controller (by itself), enable AHCI, and put your HDD on either the intel controller or the other sata port. If you combine the SSD with anything else on the marvell port you'll have problems, best thing to do is put the SSD solo on the marvell port. If you put an SSD on the intel port it will get errors (at least, it did for me and others i've known to do this)

What kinda temps are you getting with the H80? just curiuos, was thinking of getting one for my next build project.

 

[Slufa111]

I am at 4.6ghz now 5 hours prime stable @ 1.385V. Max temp is 64C and Min Temp is 26C.

What is the Marevell Controller? IS it faster? It seems to be a biggggg pain in the ass.

Marvell controller is the SATA 6GB/s controller. IIRC the white ports are p67 intel SATA 6gb/s controller designed for a raid. All I know is my SSD gets
errors and bsod's when connected (sandforce controller ssd) to the white ports, but work fine on the marvell. Your mileage may vary of course
