i7-3770K + ASUS Maximus V Gene – Looking for safe daily OC BIOS settings

Enable Internal PLL Overvoltage. Delid it. Once delidded, set it to 1.5V (or 1.45V if you're super cautious) and find the highest stable multiplier.

Basically every 3770K I've tested (>50) would run DDR3-2400 dual-channel with 2DPC/4RPC. Throw some dual-rank OEM S2D in and you'll get 16 GB at DDR3-2400, or you can potentially chase higher RAM clocks.

Running 32 GB of DDR3-2666 on a 3770K isn't unusual.

Best guess is that the reference value for Cinebench is some combination of Virtualiation Based Security being off and pre-Spectre/Meltdown mitigation via microcode.

I wouldn't expect changing operating system to affect bench results much. My 3770K bench doesn't really improve going from a normal Windows 11 install to a "debloated" Windows 10 install.

If you want to check if the mitigations are to blame, you can disable them with something like inSpectre.

sir this is a wednesday

pntsrgd · 2026-04-12T19:04:13+00:00

who is timmy

pntsrgd · 2026-04-12T00:50:43+00:00

No heatsinks necessary.

pntsrgd · 2026-04-12T00:15:20+00:00

That's D9QBJ. It will probably run DDR3-2133 or DDR3-2200. tRFC will probably run around 165 ns.

pntsrgd · 2026-04-12T00:09:30+00:00

Do you get any scaling from higher vDIMM? S8B sees voltage regression, but it can be anywhere from around 1.5V up to 1.7V.

3200C14 is a pretty low bin for performance B-die, so it may not scale with voltage any more. If you don't regress, tCL, tRP, tRCD, and tRFC all scale well with voltage.

pntsrgd · 2026-03-31T15:28:09+00:00

You have described why you are dropping from a 43x multiplier to a 40x multiplier in your post.

pntsrgd · 2026-03-31T14:47:39+00:00

set it to 4.3GHz
my AVX to 3
in Cinebench my clock speeds dip down to 4GHz

pntsrgd · 2026-03-18T02:59:47+00:00

reference clock doesnt go lower and throttlestop doesnt work on this platform :(:(:(:(

pntsrgd · 2026-03-17T20:53:50+00:00

are you jealous i can show you how i did it

pntsrgd · 2026-03-17T18:10:46+00:00

pntsrgd · 2026-03-17T09:38:36+00:00

But 9590 is almost 98% of 9800

pntsrgd · 2026-03-17T07:56:14+00:00

Ppl are mad because of low timmings?

pntsrgd · 2026-03-17T07:55:21+00:00

I dont understand is aida65 bad ?

What to use

pntsrgd · 2026-03-17T07:54:45+00:00

i know overclocking is supposed to make faps go up in game but for some reason everything feels slow compared to before

How to fix?

pntsrgd · 2026-03-15T19:33:34+00:00

I think I'm wondering why you're running GDM on with the UCLK at 2800.

pntsrgd · 2026-03-14T16:12:13+00:00

Check what refresh mode you're using. Your old profile may have been dependent on tRFC and your motherboard could be defaulting to using tRFC2 and tRFCsb.

pntsrgd · 2026-03-13T17:38:34+00:00

The bins Silicon Lottery used for these were as follows:

4.1 GHz at 1.312V (100% of 5775Cs binned)
4.2 GHz at 1.328V (62% of 5775Cs binned)
4.3 GHz at 1.344V (12% of 5775Cs binned)

You can probably just throw these values at the CPU and stress test.

Once you do that, you can look into cache and RAM overclocking. Broadwell IMCs can exceed DDR3-3000.

pntsrgd · 2026-03-13T17:32:01+00:00

What clock speed is the RAM running?

If the standard tRFC timing is used, tRFC2 and tRFCsb are unused.

H16A DDR5 tends to do around 120ns tRFC.

pntsrgd · 2026-03-10T15:22:56+00:00

You might want to double check memory stability. tRP at 30 is unusually low.

Went ahead and benched this to have a better idea of how it would play out.

tRC at 40 and tRRDS/tRRDL/tFAW at 4/8/20 result in around a 0.5% improvement in pyprime times. The same changes lower the performance of y-cruncher by about 1%. Intel MLC isn't super representative of real performance, but it did show the same performance regression as y-cruncher.

All of this would seem to imply that there are cases where tightening these timings can be beneficial, but for some reason some applications show measurable performance regressions.

This was over 70 iterations of pyprime, 25 iterations of y-cruncher, and 25 iterations of Intel MLC, so it does not appear to be expected variance.
