SideShow: E5200 Overclock Log

[reishoto]

---

With this experience I occasionally misspelled Gigabyte to Gaygabite for some odd reasons

and for very good reason, i might as well spell it this way like u do master, hehehe...

[simoko]

regarding sa fsb wall question yesterday, i was testing it on e 6500K and I am very close to 500 fsb but couldn't surpass it

try playing w/ these parameters:

CPU Clock Skew = 100ps (0 picosec man tingali default ana)
NB Clock Skew = normal

ikaw nalang timpla2x...i am assuming that you have played w/ the Vcore & Vtt params...i will email you the explanation later including a spreadsheet for setting the GTLRef parameters...lakaw sa ko...ngita pa moolah...post results unya...

polds, the results you posted helped in confirming on top of my head that even processor in the same batches does not overclock or yields the same results OR it could also be that certain brands of motherboards shines more than the others. It's fun discovering and learning new things along the way and helps in slowing down the aging process

mao gani nga swerte-swerte ra jud ni bai kay even if you get a nice processor, ang board ang conked out so its still not an assurance that you'll clock high with a known golden chip. ako lang na notice sa board kay nice kaayo mo dala ug memory. i can easily drop tRD timings (sa memory controller) down to 5 for a 333 strap with minimal or no voltage adjustments where other boards kay magkara-kara na ang memory controller ana nga latency. to get the lowest tRD for my memory controller, i had to mix and match delays para sa MCH (clock skews) so i added +100ps (pico seconds) and pumped up voltage on the chipset. tanan voltage akong gamit diri ron kay within absolute maximum sa intel kay lisod na ug wala'y rig.

voltage-wise? vdrop and vdroop in my opinion is terrible on my board! say, mag set ko ug voltage in BIOS at 1.35, init reboot ana BIOS reads it 1.33 ~ 1.34 then naa pa jud drop sa voltage gikan diha padulong sa OS ~ 1.32. pwerte nang ubusa sa voltage inig apply ug load sa processor (vDROOP) at 1. 30 nalang. i am yet t confirm this through a DMM para naa jud hardware readings pero karon tapul mode sa. the LLC implementation is also different, sa asus kay fixed dayun ang voltage tapos mo saka gamay inig load (+.05) pero sa "gaygabite" kay naa pa vDROP and then fixed na after that, when we say fixed; fixed jud nga di molihok.

OT:
@bai polds, ask lang ko walay load pa na imo 9800gt? sa ana nga gpu z? taas taas lage og temps with 60% fan speed
unsa imoha gi gamit pag flash sa bios imoha 9800gt?

nibitor ang software to modify the BIOS then xtreme tuner akong gamit pag flash sa Galaxy nga card. init man gud kaayo ug ambient temps diri bai tapos mao jud na pirmi nako makit-an nga temps sa akong card. gi-limpyohan nana nako, wa gihapon...bati lang siguro ug design ang heatsink. pwede sad nga software for a fixed overclock sa imong bios pero make sure nga stable jud as in stable kay kung dili, panington ka ug bugnaw bai. ang nakapabor lang sa galaxy nga card kay duha ang VGA BIOS so kung mupalpak ka, naa keystroke to restore your copy.

@poldo

ot lng ko gamay, bai polds rev 1.1 na imung Gigabyte GAEP45-UD3R mobo? nice OC btw.

yeah, revision 1.1 bai. thanks. i don't plan on leaving it at that voltage, though. i already set it to 3.8 GHz kay 1.36 volts sa BIOS, 1.33 in CPU-Z then 1.28 inig vDROOP which for me is sakto kaayo sa akong panlasa. dili na worth ang extra voltage ug extra frequency for 4 GHz, dota, starcraft ug simulators ra duwaan.

aw mao ba e on to imo aircon oi 5 HP hahaha nag ask lang ko kay kato sa akoa videocard kay 47 to 50 man ma detect sa gpuz idle....

ahhh ok try nako og flash bios ato kay 25% ra ang stock fan speed niya
maglagot sad ko kay dugay mo throttle to high speed maski init na.... akoa gi furmark sus abot 80 deg gud
pero ang fan naa ra sa 85% lagot ko hehehehe

if ma pusoy no probs ra nako hahaha mapulihan pa man sad


sakto gyud ng gigaybyte vdrop tirada gyud hehehe

[poldopunk]

sakto kaayo ang nibitor bai kay mo read sa imong fan IC and then ma set nimo ang mga parameters like when mo full speed ang fan and at what temperature pero magdepende pud ni sa IC nga gigamit sa card.

up this thread. still reading this one.

i stopped searching for the highest frequency attainable with absolute maximum voltage specifications seeing that i would have to go beyond 1.45 volts to go higher than 4.2GHz. right now, its back to scratch and i'm currently running multiple tests to verify stability. the tests will include the following:

- Prime95 Small FFTs to verify overclock stability of the processor
- Prime95 Large FFTs to verify overclock stability of the memory controller, fsb and portions of the memory (goal is to get the lowest tRD latency possible)
- Prime95 Blend test, to verify the overall stability of the system; processor, mch and memory.

the first overclock which was 266 x 12.5 with voltage adjustments passes with Intel Burn Test. I'm sure it'll pass with Prime95 Small FFTs since the IBT is much more torturous. I tested the overclock with large FFTs and auto-configured tRD latency for the MCH and DDR2-800 CAS4 for the memory and this is what i had earlier:

Spoiler! 

this pretty much is the sweetest overclock with no voltage adjustments so i'll work on fine tuning and lowering tRD latency as well as other memory sub-timings (tRFC). kung naa mo react sa akong stability test, lain-lain ta ug interpretation sa stable; and my tests are what i considered stable...to each his own kumbaga.

this is the memory and cache benchark sa everest with tRD (Common Performance Level) at 5:

Spoiler!

nice bai polds hehehe akoa pod gipangita pagpa stable sa akoa memory nga tight timings hehehe
experiment2 ba need more time lang gyud pero lingaw kaayo hehehehe

[centax error]

polds, very stable na kaayo na imo 5200, on my PC if maka sulod lang ko sa istorya.net and maka stream sa youp**n.com then that's stable enough for me

[dmelsie]

@CE hahaha pagka amew sad baya ana oi heheheh unsaon na lang pod na

nice bitaw ang E5200 mao mana ta akoa target kuhaon sauna nagkuha na gud ko og mobo pareha ka poldo kaso nitunga man tong 550 gud mao gi cancel na lang
