Thanks for the help, folks! biggrin.gif

It turns out... it was exactly as I expected- I seated the ram improperly. After a long day of work (and being an unofficial therapist), I sat down, took a good look at my case, pulled out the old G.Skill sticks, popped in the delicious Samsung ones, paid careful attention to how I would be seating them... and noticed something a little different from the last night.

Apparently in my haste, I did not seat the "unsecured" part of the ram all the way in, which caused my no post issue.

Now, I am happy... and now considering buying a second pair off Samsung ram off Amazon (they are selling the individual sticks for really cheap right now!) thumb.gif

Yes, but yesterday, they were selling for a little over $15.

I bought two individual sticks and they are running without issue... aside from my own mistake, of course. wink.gif

Okay, cool. They were a buck more but I went ahead and ordered two sticks mostly out of curiosity. I had first heard about them from a friend over on the M2N32 club. It's likely these will arrive on Wed next week well before my replacement Sniper.

If you overclock them, and I understand these are supposed to be good up to 2400MHz, would you kindly share your BIOS settings used?

Thx

Just upgraded to a FX-8350



Updated my build log with a few other pics as well

if you got a minute........
need a little help here, im actually waiting to know for sure, should i get the CH5 formula or CH5 Z
just got my fx8350 i already tried it in my CH4 extreme nice, but want better board 990fx chipset
whats the defference in the CH5 and CH5 Z
Thanks!

I hadn't seen that review, so thanks. Interesting, especially the comments around which Vishera cores to disable for overclocking.

I don't have a C4F and so will not comment on it other than to note I remember someone saying that board had a NB fan for the heatsink. I don't know how well it performed or how hot the chipset was. If you're coming to a C5F board and intend to get into higher-end overclocking, you will need to find a way to keep the NB chipset cooled.

Coincidentally, I am seeing that the machine overall is pretty sensitive to ambient temps. A cold front moved through south Florida and it's gotten downright cold. Indoors presently it is 16C and my NB is at a relatively cool 41C with my ad-hoc supplemental cooling fan.

Hi Everyone.

First off, I want to wish all of you a joyous holiday season.

I'm looking for suggestions to help with stability during overclocking when it comes to the effect of memory. Part of the issue that needs to be overcome here is tying overall system performance across all the components, coupled with the fact that I'm still trying to learn this AM3+ board. In this post, the focus is on the effect of DRAM timings and basic overclocking techniques as applied to DRAM.

As you may recall, I claimed my system was Prime95 stable at 4.8GHz, and so for the purposes this discussion, we'll use this CPU speed as a basis for the OC experiments. Also removed 2 of the 4 Sniper sticks to simplify the excercise. For the experienced overclocker, none of this will be earth shattering news, but for those starting out these points might be helpful.
What I'm realizing now is that when starting out with BIOS settings mostly on Automatic selection, the DRAM timings are not set to the manufacturer's settings stored in the profile on the chips. That's remedied by selecting DOCP in AI Overclock Tuner.

With my initial stability runs, timings were set to 11-11-11-28 @1.5V by BIOS, although the stated rating by G.Skill is 9-9-9-24@1.5V. In other words, the BIOS on the C5F will give the former settings on Auto and Manual Tuner modes, but will properly use the latter timings when choosing DOCP and selecting the DRAM profile.

Now we move on to using DOCP with the proper DRAM timings per the mfr specs. Except now I can no longer achieve a 10 pass IBT run with the system freezing within pass 2-4. Apparently when stressing the CPU frequency, the DRAM becomes more sensitive from a stability perspective, at least that's the way it appears from this cockpit. So here's the question.

To counteract the effects of the instability at higher CPU frequencies, is increasing Drive Strength and DRAM voltage necessary and both needed? Are there any other knobs to consider.

It is my understanding that these Snipers can take up to 1.65V, although I'm apprehensive of going that high. However, if that's the only way to achieve the improved performance, I'd consider doing it.
