Need some advice on voltage scaling with 4000+ ClawHammer.
Last I had it running, 1.620v at 2688mhz, But I think I was using a not so good memory divider.... Not sure, I have only 1 bench with the chip. Couldn't keep focused on it at the time.
Would it be feasible to run say 1.8v - 1.9v on sub ambient but above freezing on 130nm? (The cpu is not installed yet. Had to clean it up, has a couple wavy pins. Maybe tonight I can swap chips after the repair.....)
It's like I made that vid. Basic tweaks for Pifast on a Claw with BH-5 ram. Or any 939 with BH-5 for that matter. I actually tweak a little harder than that.
The 148 will do 2-2-2-0-9. This 4000+ with the same timings just boot cycles.
Probably could run the 150 divider and tune the sub timings.... However. The board with the nodded bios, as you saw in the beginning was at defaults. Way strange timings. When set to auto all. 2-3-2-5-12 are the timings that belong there.
I did reflash the board, but clear cmos sets 4-0-4-4 or w/e. The only sticks it will post with are my XMS. The Adata wont post at all at defaults. Gotta set profile and then hot swap the memory, can get the Adata to run. Havent tested them on this chip yet.
antinomy: I think you should start a topic on this one. It could be several reasons you need to check - memory, Vio, badly clocking CPU.

austin86: Stuck in the low/mid 170s and the system is stablish when booted of a floppy to about 180. IDK maybe I need to just toss deice/ln2 at it.

austin86: Does anyone know of a ISA VGA/IDE card? trying to hit a record on FSB with 440bx and I keep getting held back by the on board IDE, I tried a ide to sada adapter and I got further but not by much.

antinomy: What test? It could be because of AGESA version or maybe some security patches for the CPU.

george: And it was not a temp issue as far I could see.

george: wth? Updated to latest BIOS version on the A520, did a few bench with cpu-z after that, hmm, results lowered, anyhow got the Ram settled ok. However, increased the CPU some 5MHz, bench result went down? Perhaps forgot some settings I had.(This W10)
