Still waiting, for some reason UPS in california took 3 days just to ship it out. It happens, its on time for monday delivery though and its at my local UPS right now.

 

Two things Im gonna note in the review already. 1 at first newegg and biostar site said ddrII800 was max. But the press release for the biostar TA770 said ddrII 1066. I left review on newegg and even corrected it to ddrII800 because of newegg and biostar spec listing. NOW it says DDRII1066 on biostar.....but still ddrII 800 on newegg, odd.

MEMORY

 

Support Dual Channel DDR2 533/667/800/1066 MHz

4 x DDR2 DIMM Memory Slot

Max. Supports up to 8GB Memory

Taipei, Taiwan (techmessenger.com) -- BIOSTAR Microtech Int'l Corp., a professional manufacturer of motherboards has launched T-Series TA770 A2+, based on the latest AMD 770 Chipset. The model supports the upcoming AMD Phenom™ series multi-core processors, which support Dual Channel DDR2-1066, bigger L3 cache and offer optimized overclocking ability.

 

 

2, newegg says discontinued now (check my link) I think its only been out few days to a month.

 

Maybe they messed up the box label? Maybe newegg put ddrII 800 as spec due to box. This may have been a mess, with customers RMA thinking it was 800 not ddrII 1066. I contacted newegg on this and should have a answer by monday evening when review is done.

Hi everyone!

 

I have had this board for just over one week now and also the C4 version of Xtreeme's Corsair memory so thought I would throw in a few cents...

I have managed to get my mem to DDR1066 but this board has an under-par bios which limits its overclock-ability!

Some cpu multipliers do not like some settings and it seems fsb limited at different memory dividers and yes it does have a DDR1066 divider.

 

@ RAM GUY: If you could answer this for me...I can get to the 1066 mark on these 800 modules but when I set the mem/@ 1066 (cpu/5) timings 5-5-5-18, I can run fsb @ 231, cpu*@11.5 yeilds memf of ~531Mhz. Boots/runs/benches/games fine...bump up the fsb to 235 triggers safe boot...change CAS to 6 @235 and boots fine...bump up the fsb to 240 and safe boots.

I can loosen any timings and have pushed the vdimm to the 2.57 and still nothing.

Is this just the limit of the chip or is it because it is not rated for cas6?

Can I change the SPD to accept cas4/5&6 over the already programmed 4&5? or is it not going to help any?

 

Maybe recommend another Corsair DDR2 module that would yield me over 10GB read/write/copy bandwidth?

 

Ohh, btw the actual bios vdimm for this board are a little off, review the following:

BIOS ACTUAL

2.10V = 1.85V

2.20V = 1.9xV

2.30V = 2.0xV

2.40V = 2.1xV

2.50V = 2.22V

2.60V = 2.35V

2.70V = 2.44V

2.90V = 2.57V

 

Thanks, TMDT!

I have not seen that MB but if that is true I would suggest talking to them about getting it replaced.

Yes, so it seems that from other sources that my board is drastically undervolting on vdimm.

For those who would like to test their board you can measure vdimm from the right leg of this fet: (disregard the ?-mark)

OK, So I ended up RMAing the board on the Thursday after my last post. Biostar did reply the day I messaged them asking if the board was showing any stability problems which at defaults or with the memory timings set manually to EPP it wasn't, my concern was the overclocking of the product and my obvious discovery of the undervolting on the memory voltage circuit. Needless to say I never received a reply to my followup email.

So after 10+ days twiddling my thumbs I received my replacement board and upon testing of the vdimm, this one is only ~-0.05 on vdimm.

I need some replacement 9V batteries for some of my other testing equipment so further progress is hindered for another day.

 

Thanks for your input R-G!

 

We live to overclock another day!!!
