Bbse, with psc, at least mine, I can't pass 370

Ok I did some test with ud7 ver 2.0 and bios f5a I tested 3 145, one stopped at 410 second stopped at 412 and the last stopped at 449 ? All tested with same profile, with dram set to ganged mode. For this I set vcore 1.45 cpu-nb 1.375 dram 1.79 I used stock cooler plus a 120mm fan to cooling dram/nb. https://hwbot.org/submission/4320473_cnzdrn_reference_frequency_ga_890fxa_ud7_448.98_mhz Next step try with hyper and unganged.

I will try d9's when I will find some sticks. High vdimm for me is useless, with sempron from 1.72 to 1.85 I give same reference. It's chip related. Same settings give me 435 fsb geekbench 3 with 960t at 1.81vdimm. https://hwbot.org/submission/4258887_cnzdrn_reference_frequency_ga_890fxa_ud7_437.99_mhz/ I think some chip have better imc, I just need to find another one With ud7 and biostar 890fx I never lost dual channel, only with asus or 990fx ud3 I see that problem.

The main problem you have is dram. For bclk with ud7 my best result is based on elpida hyper, high binned hyper, bbse is good and psc is the worst dram to use. All sempron 145/150 that I tested can do atleast 408 dual unganged or 415 dual ganged. Single stick can do the same you can do with ganged. Best stick slot 3, the second slot 4. I bin each stick individually, max boot and max on Windows. PS I use ud7 rev 2.1 maybe rev 2.0 works different PS 2 cpu-nb is the imc voltage, if you set 1,3-1,35v you can do about 2800 imc freq and push dram to max reference they can do

I tested some sabertooth bios. The 1903 seems more stable on ln2. On air I reach the same reference.

For fsb on am3 I did: 890fx ud7 max fsb 435 (with 960t geek3, 412 sempron), Saber r2 / cross 5z 420+ (with sempron) m4a89gtd 430 ( with ganged weak performance). With cross 4f 4e 5f I'm unable to do 400. Biostar 890fxe can do 420+ but have serious problem for cpu-nb clocking.

Crosshair 5z can do at least 420 unganged, if your chip scale like my old chip 430+ seems doable ?

Very nice! You really need an am3 board!

Maybe problem of c2 stepping on 64bit?

Thank you :) This chip isn't so good :(

Wow really strong chip man!

I'll try mine asap, I have trouble with imc last time I used.

Well done!

This is strong score!

I push more voltage on vcore

Thanks

With am3 board ganged help to raise ref clock. Cb is chip related, some chip won't work well on cold.

You killed all my scores! Well done :)

YGPM

Bump

Very nice score!

Well done man!

Sold to Albrecht ?

Nice score! Ud7 rocks on geekbench :)

For sale an i7 7700k that can do 6,79 GHz cinebench r15. Chip is boxed ad dellidded, I clean it so no tim under ihs. Cpu is cb and cbb free (if you raise pll termination) at least on apex IX. Price is 400€ shipped in UE, offers are welcome. For payment Bank transfert or PayPal (buyer cover fee) Thank you, Adriano.
