I have F3-17000CL9D from G.Skill (2 4GB chips in slot A2 and B2) and ASRock Z77 Extreme 6 motherboard (i7 3770K).. setting the RAM timings to what it's rated at in BIOS gives me immediate errors when running Prime95 after a few seconds. This happens w/ and w/o OC. Any help would be greatly appreciated.

Thanks,

According to the Gskill website:

Your ram is rated at DDR3-2133 MHz (PC3-17000), with a 9-11-9-28 2N timing at 1.65V. But if you are having issues with it, the SPD is 1600MHz with 9-9-9-24-2N at 1.5V. Have you tried the SPD?

Thanks,

I would hit the clear CMOS button to reset all bios settings. Then set XMP profile and your ram voltage. After that run memtest as others have mentioned

If that's the case (and I'm pretty certain it is), your only way to stabilize your overclock would be tucking a fan on the heatspreader next to the socket, or at least pointing a fan in that direction. Although the former is much more effective. It doesn't even have to be huge fan, I'm using a 60mm slim one @7V.

That was helpful indeed. Aside from the part about needing to stick another fan down there, that part won't be easy since I have an open air rig. And no spare fan.

I was kind of wondering if that might be it. I can't get it stable above 3.8. Unfortunately, it's too late to bring the board back, so at some point I'll just have to sell and replace. I'm pretty much fine with that, I've never had a great experience with an Asrock board while overclocking.

Is there any merit at all to the idea that it could be the processor throttling itself due to some sort of failure?

I have ziptied that fan to the heat pipes of my CPU cooler to keep it in place. You really shouldn't give up because of a $5 fan. Ghetto mod for life! wink.gif

Of course there's always the possibility that the chip or the board is malfunctioning, and 3.8 is quite for the throttling to kick in.
You could try to place a fan... well, a ventilator to blow some air onto the relevant parts of the board and see if that does any good. Or since you already have an open case (pics please! Would love to see that!) you could also try to touch the heat spreader. But beware, it could be quite hot. According to overclockers.ru the board begins to throttle if the modules reach around 64C, which is even lower than on the Pro3 (for which I think it was at 75C).

Only for 2 hours. I just got a new SSD and have been busy with work. I think the temp max was in the high 60's. Never went over 70. Hope to run it again this weekend. I removed both drive cages in my R4 and have two 2.5" drives. I use a drive dock for my big 3.5" drives. Only one GPU. So it all stays plenty cool with fan speeds at 5v.

Right on, try to let it run 8-12 hours on the next run to make sure your fully stable. Temps look good thumb.gif

I want to reach 4.8ghz stable on my delidded 3770k. Temps are fine regardless of voltages. I just need to know whether to go fixed or offset. I think ill like offset better, however i dont know what voltages should use in offset value. The guide doesnt tell me to change it but when i look around forums some people who have 4.6ghz above have it changed. Also turbo boost should be where? I already moved up 6 spots to +0.023v and it still unstable. Its ok to go much further on turbo boost? And should i change the offset volt too? If so around what value for 4.8ghz

every chip is different. there is no fixed offset value
if you use the search feature on the forum, you can find many offset voltage guides in this subforum

Two things that will help us help you:

1.Fill out rigbuilder and attach your rig to your sig. This helps us quick spot your hardware config
2.Grab BIOS screenshots and post them up here. This will allows to see how you have overclocked your rig, so we can make suggestions.

Rigbuilder is on the top right hand corner of the page. To take screenies in bios, format a thumb drive in FAT32 and hit f12 in BIOS.

No one can tell you which Offset / Turbo value will be ok for your chip, it all depends on how much Vcore will eventually be delivered to your CPU.
Use CPU-Z or Open Hardware Monitor to find out your Vcore under load.
