الحاجه الغريبه اني رحت لموقع انتل لمشاهدة الفولت المسموح بيه لهذه المعالجات فلم اجده :ah32:
فما معنى ذلك؟:ah35:
وفي نفس الوقت انتل بتقول احرق والضمان مكفول :o

بالضبط اصبت عزيزي خير الدين المشكله عندنا ودي حاجه الكل هنا بالمنتدى بيركز عليها

[ey@d-i7]

هل هناك مشاكل أو ما شابه حول هذه الدفعة الجديدة من انتل ...؟

لا أفهم مالذي يقلقكم شباب ؟ حدود الفولت المسموحة ؟

لا أخي عمر
القصة ان عدد من المستخدمين خسروا معالجاتهم بعد او كسر السرعة بعد عدد من الأيام فقط

[mahdi611]

اخي جينوورد الذي يقلق هنا ان عملية موت المعالجات بهذه السهوله وبفولتات لا تصل ل 1.39
ايضا عملية كسر سرعة المعالج يظهر ان لها طريقه شويه مختلفه وحساسه ولا تنسى اننا سنخرج من فوج من المعالجات كنا نصل بها الى 1.4 فولت وكانت حريقه شغل وبنحرت عليها بشتى برامج البنشمارك لاختبار قوة ادائها لنصل الى هذه الفئه الجديده لسه حتبقى ايدينا تقيله عليها بالكسر دي حتى عاوزالها فولت محدد للرامات لا يتجاوز ال 1.6 الى هذه الدرجه تتمتع بالحساسيه؟

بكل بساطة Intel ستجبرنا على شراء النسخ الK

المشكلة أن هذه المعالجات هي الK

[Eng.MinaEdward]

عيب تصنيع ؟؟؟؟!

ام اجبار على ايقاف جنون الاوفر كلوك ؟؟؟!

هل انتل بدأت "تخرف" فى موضوع كسر السرعة

ام تخزن كل ما لديها لمنصات 2011 وتعتبر هذة الفئة الان مجرد فئة متوسطة وغير مطلوب منها ضغط رهيب ؟؟؟!

Hi there

I've spoke to Intel this morning and got the following answers from them:-

1. Anything over 1.40v on air is risky, upto 1.50v on water should be OK but risky.
2. Anything over 1.50v on memory is not recommended but should not kill a CPU.
3. Clocking on BCLK is highly un-recommended due to onboard graphics.

So the biggest factory they say is vcore, pushing above 1.40v is a risk, therefor I'd say don't go beyond 1.35v. BCLK clocking is a no no for sure.

I've asked for documents regarding 1.50v as motherboards manufacturers seem to think 1.65v is the safe limit, though Intel are saying 1.50v is more advisable.

I am going to update all our CPU descriptions with this information.

Anyone with 1.6-1.7v memory should run the memory at 1.50v as in theory it will run fine at those voltage as all memory manufacturers are now on new IC's.

تحديث

In our own testing we have found the only thing killing the CPU's is core voltage. We've found setting memory voltage at 1.65v seems to be doing no harm, but were now gonna setup 3 rigs, one with 1.45v core volts, one with BCLK overclocking and one with 1.65 memory clock to see which one if any dies first. We shall do this on 2500k chips

Another update:-

Intel recommend 1.50v for all their I5 and I7 processors, not just Sandybridge, which makes us further believe the culprit for dead CPU's exceeding 1.35-1.40v range on vcore

Right guys myself and our technical guys have spent the entire weekend and this morning in discussions with Intel regarding the alarming amount of reports of Sandybridge CPU's dying and have been conducting our own testing as have Intel to find out what is a definite no no.


Sandybridge maximum safe voltages

Core Voltage - Not recommended too exceed 1.38v, doing so could kill the CPU, we therefor recommend a range of 1.325-1.350v if overclocking.
Memory Voltage - Intel recommend 1.50v plus/minus 5% which means upto 1.58v is the safe recommended limit. In our testing we have found 1.65v has caused no issues.
BCLK Base Clock - This is strictly a NO, anyone using base clock overclocking could/will cause damange to CPU/Mainboard. (Set manually to 100)
PLL Voltage - Do not exceed 1.9v!!



Processor - Basically we recommend customers not to exceed 1.35v to play it safe, all our bundles are set at 1.3250v or lower, any competitors offering bundles above 4.6GHz you should be enquiring as to what voltage they are using as we believe anything over 1.38v will limit CPU lifespan and anything over 1.42v will likely kill the CPU or severely limit its lifespan.

Memory - Intel recommend 1.50v plus/minus 5% which means 1.60v is the ideal safe maximum, but we have found in our testing all 1.65v memory is fine. We have also found most new 1.65v like Corsair XMS3 will run at its rated timings with just 1.50-1.55v which is well within Intel specifications. So people upgrading to Sandybridge you can still use your old DDR3, but we do recommend you run it at 1.60v or less. We are shipping most of our bundles which feature Corsair XMS at 1.50v-1.55v at rated timings. We've also discussed with Asus and MSI regarding voltages for memory and they also confirm in their testing 1.65v caused no issues with reliability.

Base Clock - To put it simple if you value the life of your components, do not overclock using base clock!

PLL Voltage - Again do not exceed 1.9v!


These are just guidelines we recommend you follow, if you want to push more voltage through your CPU's then just be aware they could die on you. Your warranty is un-affected and we will honor any CPU's that die, we just won't ask questions as to how you killed them.

Not all CPU's are as fragile as others, we have experimented upto 1.50v Vcore and 1.70v memory and had zero issues with reliability, so it seems some of fine when pushing hard

Hi there

Well our system is still prime stable with memory set at 1.65v, its been running now for over 24hrs under constant load and no signs of flaking or falling over

ما سبب هذه الحساسية العالية لأي أوفركلوك و المحدودية في الفولتية ؟ وهل تعتبر هذه نقطة ضعف كبيرة ستؤثر على انتشار هذه الدفعة‏SB ‎‏ من انتل‎ ‎؟
