A64 tweaker help (kingston value ram)

[fatfreepork]

hi, i need a little help with A64 tweaker values.

Has anybody here tried with Kingston value ram pc3200? Stock latencies at 3-4-4-8 and there are so many numbers available to tweak that it gets a little confusing.

My knowledge is a little more limited to nf2 tweaker.

Here is a shot of A64 tweaker.

My first goal is to get the memory running at 200Mhz (stock) because bios (chaintech vnf3 250gb) only allows 166 or 133. Im guessing i need to change the tREF, but then theres 200mhz 15.6us, 7.8us, 3.9us, and 1.95us so this is really confusing!

Is there a little guide that explains each value?

I suggest that someone makes a nifty little page with good settings with each ram.


THanks in advance.

okay i just changed the MEMCLK frequency to 200Mhz and the computer froze.

-edit- oh an btw, its not 2gb like my sig says. Currently its running 2x512 because when i have 2x1gb, the memory will run at 133Mhz and it feels the same as 1gb at 166Mhz so i took out the 1gb sticks in favor of these 512's.

okay, these are winbond chips. bh5 im guessing.

BH-5 probably won't boot @ cas3 ;).

How old are these kingston sticks?

and then what kingston has to say about utt

Question of the Month

Industry price reports often refer to UTT DRAMs. What are they?

Because DRAM memory prices are depressed, the industry has seen steady growth in the supply and use of UTT (or Untested) DRAMs. Basically, these are not premium-quality DRAMs. Instead, they are DRAMs that have skipped major testing steps in their manufacturing process.

Due to the low prices, some DRAM manufacturers can cut 15 to 20 percent in costs per DRAM by skipping DRAM chip reliability burn-in and speed/functionality testing on high-end chip testers. The result is UTT DRAM chips of unknown quality that are often Non-Conforming (NCs) as well (meaning that they do not conform to JEDEC specifications).

The UTT DRAMs are then sold to brokers who dump them in different parts of the world. Many third-party memory module manufacturers buy them and build low-cost modules. These manufacturers generally do not have the multimillion dollar DRAM chip testers required to retest the UTT DRAMs.

Kingston's philosophy is different. Kingston is among the world's largest buyers of DRAM chips directly from the DRAM manufacturers, much like Dell, HP, and IBM. With quality as a priority, Kingston buys "full spec" DRAMs that have been fully tested and warranted by the DRAM manufacturers. Kingston also buys memory wafers and packages them into chips at its wafer back-end facilities. Among these facilities is Powertech Technology Inc. (PTI), a strategic partner in Taiwan which has high-volume wafer back-end processing capabilities. PTI's Taiwan facilities house tens of millions of dollars in DRAM chip testers, which are used to ensure that the DRAMs packaged there for Kingston are full spec.

Kingston views the low cost of UTT DRAMs as the price floor of the industry. Fully tested, "full spec" DRAMs from the DRAM manufacturers are always more expensive. Comparing the low prices of memory modules using UTT DRAMs and Kingston's memory modules is like comparing apples to oranges. This is why Kingston, despite its high unit volumes, will rarely offer the lowest memory prices. Remember, the lowest priced memory modules are generally not full quality.

i go back to try under 3.0vdimm. quick testing shows 2-3-3-8 at 2.88vdimm to be fine at superpi1m. trying 2-2-2-8 results in memdump and various other windows components not loading.


so that basically says its utt, or not? as according to kingston, no utt is used in their memory.

okay, so i have 3 sets of these, (6 sticks total). i dont know where to begin. but i really want to find out what chips these are. Maybe i will phone kingston and ask.

not bh5 (boots at cas3)
not utt (according to kingston)

so wtf its ch5? chips are relabled winbond. Only signs of winbond are the two dimples.

Infenion 5ns looks alot like Winbond since they use their fabs now

Infenion B-5
http://www.techpowerup.com/memdb/img/chip16.jpg

though it dosent show up on the chip list

http://www.techpowerup.com/memdb/

[fatfreepork]

supposedly...


im pretty sure all the infineons chips ive seen dont have winbond dimples.

[13oost]

:stick: just posting what the pic shows and a few things ive read.... that pic is infenion b-5 and it does have the windbond dimples, though its near impossible to find much on this chip, havent found much on google after hours of searching

idk if this will help, but does it have the 2 solderballs on the bottom of the chip like winbond does (infenion B-5 may have these also, but it will totally rule out any chance of winbond if they dont have the 2 solder balls)

[fatfreepork]

i never posted a pic of the ram. I will be later today though.

[13oost]

er, no... the pic i posted
http://www.techpowerup.com/memdb/img/chip16.jpg
^that pic is Infenion B-5^

[easypanic]

That would help even more ;)

[fatfreepork]

oh woops lol. anyhow it doesnt say infineons on the chips.

Model number is Kingston b11444.02

d3208dw3t-5u

0449pt01

[13oost]

yea, but could be a rebrand....

my ocz value ram is rebranded winbond BH-5... they even flushed all the info out of the chips, no sn, no week... cant find jack w/ software programs

could be some junk CH-5, but it sounds like an un-named chip on that, thats not on any lists

Kingston Ram w/remarked Chips as D328DW-5 Winbond BH-5
ironic resemblance, but that cant be BH-5 if it boots at cas3
