FYI, the venice E6 is the first to have SSE3 support.

weird, my CPU-Z says my E3 supports SSE3 too, is that a bug? blink.gif

btw, since i'm too damn lazy to read up tongue.gif is there any real advantage of SSE3?

hmm...how come it is so unfair, last time when i posted my spec and ask for OC advice, the mod ask me to post in the Q&A session, and close the thread. Then how come now can posted and ask for advice again? sad.gif I posted in Q&A session also no one respond to it.

Anyhow, just share some experience with you. I m using Kingston ValueRam also can it can hit fsb 400 on my T-bred 2600+ (default FSB is only 266) by applying 2.7Vdimm. Running stable and passed 3DMark, PCMark, Prime95 tests.

Read your post there before, it's totally not related to what that thread is meant for
That's why u dont get any replies

hrmmm..ok. You mean retain my overall speed to like 1.8g and increase the HTT while maintaining the multi? ok

Juice is more than enough. i think more than 2.8 for a KVR is overkill. will try it out after CNY. didnt bring my pc back to hometown
*
would be a lot easier to just lower the multi to about 3X right away though sweat.gif

no such thing as all Venices hit 2.5ghz easily
plus, he said his winnie = Winchester

yeah, HTT multi has gotta come down
3X would be ideal to find the max speed of your proc

and i hope u realise that only a few steppings around here i've seen go up to 2.8ghz

pretty unusual
did u put dividers on your rams?
try 166 or 133 to find your max CPU speed

hi,
i'm also new to OC. check out my OC'ed ram timing. from 166mhz to 222mhz with even tighter timing...

btw, my cpu temp after an hour of prime95 is 62C sweat.gif . idle is 42C. need a new HSF?
thinkin of acquire one zalman fan but afraid it wont fit into my casing sweat.gif
*
try looking for temp readings from other users of your same board
it *might* be over reporting the temps

Pros, pls help me here. I got a64 eng sample & 2 stick of cheapo apacer 512M ram. One of the stick is pc2700 and another is pc3200.
Here's the pic from cpuz:

I can't get the ram run in dual channel (mobo beep)
If i wanna get my proc running in 2.4ghz, do i just set the multiplier to 12 (up the voltage if required) without applying the mem divider coz i leave HTT @200?
*
Wow, that's weird
have u tried with a different proc?
maybe the ES' mem controller a little screwed up or something

yes u can just up the multi to 12X and leave the HTT
that way u wont be overclocking your rams

got question here, what if we overclocking our rig using 5:6 ratio(166Mhz) for RAMs & run at 270HTT, for sure in cpu-z, memory tab will show the frequency of RAMs at 225Mhz. my question :-

1. is the 225Mhz equivalent to DDR450??
2. if yes, izzit means our RAMs been 225Mhz(ddr450) & running at the current overclocked cpu speed example 2.7Ghz were equivalent to 2.0Ghz(default) running on ddr400 execpt bonus to the clock speed??
*
how could it be possible that 225mhz is equal to 200mhz?
if it is, then whats the point in overclocking?

I am just wondering, is it possible to overclock an AMD64 3700+ S754?

I am currently using an Asus K8N-E, with 1 Corsair PC3200 CL2.5 and 1 Corsair PC3200 CL2. Board is running at DDR333. PSU is Enermax 460W FMA.

1. Is the CPU multiplier unlocked?
2. What does it mean by DDR333? What I know is it runs at the same cpu speed??
3. Even if its a minor overclock, can I say, overclock the ram, but with a lower   
    multiplier, achieving result of around 2.4ghz as well? Does that increase
    performance?
4. I might want to upgrade to 2GB memory, what kind of rams are good for an average
    OCer (I know this cpu cant o/c much), and what's the average price for these rams?
Thanks in advance, sorry for the noobish questions. Its been awhile since I've used AMD, and that was a 1.4ghz Tbird.
*
1. As e-jump said
2. Your rams should already be at DDR400 instead of 333 even at default. Did u check with CPU-Z?
3. Yes u can. You can lower the multi and raise the HTT so that your proc speed matches it's original speed, then your rams will be overclocked. Just make sure you've set your ram dividers to 200 or 1:1 or DDR400 (whichever your board calls it)
4. Try looking for Apacer value rams with Samsung UCCC chips. They're the best price/performance rams if u can find them. How to find them? Go to shops and check their rams tongue.gif yeah it sux

i'm super noob here...

my rig..

cant go more than 239 fsb..

239fsb setting....- mem 200 = 478mghz 3.3.3.7 @ 2.7v [corsair xms 3200 pro led]                    rev5.2
                        - HTT 4x
                        - proc ratio 8x
                        - proc vCore 1.492

240 setting - blank-bios blank...
                - so i raise vCore..still da same..

did i miss something rclxub.gif

Keep your proc multi at 9X
Lower your RAM multi to 166 or whatever your mobo calls it
Should be called something like FSB : DRAM

250fsb @ 250 mhz ram(500). timing 3.3.3.8 @ 2.8v

vcore 1.490..
but sumthing wierd. i set proc multiplier to 8x...@ bios...when boot up .to windows...n see @ CPU-z still 9X  shocking.gif

did u lower your ram multi yet?

I'm guessing that's the main thing limiting your speeds now

Cause your rams probably cant go much above 250mhz, so put some lower dividers on them so that they'll run lower and wont limit your proc

CnQ doesnt have to be disabled when OCing
But you should disable it so that u dont have any problems

CnQ must be disabled if u plan on using a lower cpu multiplier, else it would go back to default whenever u enter windows esp if u had the A64 driver installed.

Ah...i see
But with a max multi of 9X, no one really needs to lower it sweat.gif

i'm hittin d wall w/ my ram too. sometimes lower dividers like 150, 140 wun work well (atleast in my case). no matter how loose d timin is i just can't get 'em prime stable...  sad.gif

2/1.33??? lazy to do d maths...  tongue.gif

that's 133 la sweat.gif
2/1.33 = 200/133 (HTT / RAM speed)
